Fantasy Baseball Breakouts or Fake Outs? Hitters Delivering Elite Results For Week 8

May 19, 2026

Kevin analyzes hitter fantasy baseball sleepers, breakouts surging for Week 8 of 2026. Are they true breakouts, or fake outs? Read his fantasy baseball outlooks and buys/sells.

Here we go with another edition of Fantasy Baseball Hitter Breakouts or Fake Outs. Truth be told, this is my favorite weekly article to write because the deep dive analysis always forces me to learn so much more about so many different players around the league. You love the payoff of what the analysis can do for your fantasy roster and simply getting to analyze these players is just as much of a payoff for me.

I've discovered some of my favorite players through writing this article, James Wood being the top of the list for me as a "new" discovery through breakouts or fake outs. So with each week I'm always hopeful someone new will give me a reason to follow them throughout the season. You never know who's going to become a new favorite outside of just your fantasy roster.

So with that said, let's dive into another group of hitters that are breaking out. This week, we'll evaluate a quartet of young hitters including two that we checked into last season -Gavin Sheets, Carson Benge, Ceddanne Rafaela and Jakob Marsee. All statistics in this article reflect games played through Monday, May 18th.

Gavin Sheets, OF, San Diego Padres

2026 Stats: .896 OPS, 148 OPS+, 9 HR, 21 RBI, 19 R, 3 SB

Oh, you thought the offensive leader of the Padres would be Manny Machado or Fernando Tatis Jr.? Guess again. Sheets is the undoubted leader of the Padres' offense right now as the leader in OPS+ and HR. He went deep twice against the Mariners on Sunday as part of a four-homer week.

He's having a career year and is one of the only Padres that's providing offensive fireworks. But as always, we need to as the question as to whether he's a fake out or a breakout. Let's dive in.

Starting with the plate approach, he's looking like the same hitter he almost always has been. His 19.9% strikeout rate is practically equivalent to 2025's rate of 19.6% while his walk rate is up from 8.1% to 9.9%. Not a tremendous increase, but any increase in walk rate is always a great sign to see.

His batted ball profile looks a bit more interesting, though, as we're seeing increases in both ground-ball rate (37.8% last season to 41.8% now) and fly-ball rate (41.1% last season to 43.9% now). That's taking away from his line drive rate which has gone from 21.1% to 14.3%.

That line drive rate would be the lowest of his career, which isn't necessarily a bad thing but we'd love to see it back near 20%. The current batted ball profile looks very similar to his 2022 season with the White Sox when he hit for a 99 OPS+.

But the big difference here is his HR/FB rate. That's now at 20.9%, the second highest mark of his career outside of his 54 game stint as a rookie in Chicago. So that's at least a noted improvement.

As far as BABIP goes, he's coming in with a .270 mark this season. Normally I'd say it would mean positive regression, but his career BABIP is at a .268 mark. This is essentially par for the course.

Heading to his Baseball Savant page we can see quite a bit of red around. His current .389 wOBA is paired with a .363 xwOBA. So some negative regression is coming and maybe that's due to the lower line drive rate. But the xwOBA still ranks in the 81st percentile, so he's going to be a really solid hitter regardless.

The barrel rate and hard-hit rate are both in the 74th percentile, so that validates what we're seeing with xwOBA. The barrel rate at 11.2% is the highest of his career while the hard-hit rate matches what he did last season. That slight increase in fly-ball rate is paying off here.

As we dive into the pitch mix we can see quite a bit of positive regression coming for two of the top pitches he faces while we also see negative regression coming for two more. Four-seamers (.344 wOBA, .419 xwOBA) and sinkers (.266 wOBA, .321 xwOBA) are where he's expecting positive regression. That gives him one excellent pitch he hits and one that's at least a decent floor.

The two pitches he's expecting negative regression against that will affect him the most are changeups (.376 wOBA, .298 xwOBA) and sliders (.675 wOBA, .417 xwOBA). Again, though, we have a pitch with an OK floor and another one that's an excellent pitch for him to hit. It's an ideal scenario!

The pitch I'd expect pitchers to start pivoting to more is the curveball. He's only got a .178 wOBA against it and just a .241 xwOBA paired with it. If they've got a good curve then Sheets is sure to face plenty of them.

Verdict: The recent hot streak surely isn't sustainable (256 wRC+ over the last 14 days), but there's still a lot to love with what Sheets is doing this season. Though his numbers in April weren't gaudy, they still added up to a 107 OPS+. That's certainly serviceable if that's his floor going forward.

I would consider Sheets a buy. At just 27% rostered in Yahoo! leagues there's a very good chance that he's on your waiver wire. There's no reason he should be that low given the current hot streak. Snag him up and ride out the hot streak. When he cools down you'll still have an above-average hitter you can prioritize in platoon matchups.

Carson Benge, OF, New York Mets

2026 Stats: .649 OPS, 85 OPS+, 3 HR, 14 RBI, 20 R, 8 SB

As the Mets' top prospect, Benge came into this season as a very intriguing player to watch. Like most of the roster for New York, his start was a big slow. But over the last two weeks he's slashing .362/.400/.489 and is the Mets' most productive regular starter in that time.

Has the Mets' No. 1 prospect gotten things figured out with this breakout? Or are the last couple weeks a fake out? Let's dig in.

Starting with his plate approach, he's posting a 20.5% strikeout rate to go along with a 7.1% walk rate. Throughout the minors in 2025 he posted a 13.1% walk rate, but at Triple-A Syracuse that rate was down to 8.7%. Given the bump to the majors, these numbers feel about right for who he is.

His batted ball profile comes in with a 45.5% ground-ball rate, 32.1% fly-ball rate and a 22.3% line drive rate. The ground-ball rate is about 4% higher than what he posted in Triple-A last year. That's resulting in a decrease in line drives, but adjustments are to be expected with a promotion to the majors.

His BABIP so far is coming in at .294, pretty close to the .300 number that we love to target. At every level of the minors, besides Triple-A, he posted a number of .320 or higher. Maybe there's some positive regression coming for Benge as he gets more and more comfortable.

Now let's head over to his Baseball Savant page to see what they say about any potential regression. And off the bat we see that maybe this hot streak is a part of positive regression that's due to him.

He's currently posting a .294 wOBA that's paired with a .310 xwOBA. Now that xwOBA only ranks in the 39th percentile, so we can't get too hyped over his current hot streak as the new standard. I think we're simply seeing him realize the positive regression xwOBA was predicting.

His barrel rate is coming in at 6.3% which is in the 34th percentile while his hard-hit rate of 42.0% sits in the 52nd percentile. I love seeing that he's at least league average with the hard-hit rate. If he can lift the ball a little more often we may see more barrels and more balls leave the yard.

As we look at the pitch mix we can see plenty of both positive and regression expected, making it for a bit of a mess to wade through. But that's what I'm here to do so we'll fight our way through this.

Four-seamers are the most important pitch to focus on here as he sees them 41.2% of the time, easily the pitch he faces the most. He's hitting them for a .319 wOBA that's paired with a .339 xwOBA. Not a ton of improvement we're set to see here, but that's still a really solid floor for a pitch he sees over 40% of the time.

The pitch he sees the second most is sinkers. He's currently been raking them for a .469 wOBA but that's paired with a .297 xwOBA. He won't be terrible against them when regression hits, but he's clearly been a beneficiary of luck here.

The next three pitches he faces are all pitches I'd expect pitchers to pivot to more often. Changeups (.189 wOBA, .289 xwOBA), sliders (.313 wOBA, .255 xwOBA) and curves (.270 wOBA, .115 xwOBA) all look to be weapons pitchers may prioritize against him when the count gets deep.

Verdict: It's important for us to simply not get way too ahead of ourselves with Benge's hot streak. He's clearly starting to get some things figured out here at the major league level and the last two weeks have been a turning point for him. But we need to realize where the ceiling is going to be for the 23-year-old and I think he ends up somewhere just below league average once he cools off.

But he's worth a flyer, especially since he's only on 22% of Yahoo! rosters. He faces Washington and Cincinnati over the next two weeks and neither are known for their pitching. Don't do anything drastic if you want to pick him up, but the next couple weeks could produce some solid results for the lefty.

Ceddanne Rafaela, OF, Boston Red Sox

2026 Stats: .786 OPS, 125 OPS+, 4 HR, 19 RBI, 18 R, 3 SB

It's been a bit ugly in Boston to start the season. That much is undeniable. But Rafaela has been doing everything he can to keep Boston's offense going, even if the rest of his teammates aren't helping to pick up the slack.

Over the last two weeks he's posted a 189 wRC+. That's appealing no matter how lackluster his teammates are. But is this a breakout we're witnessing or is it a fake out? We evaluated him last season and we're back at it again now. Let's get to it.

Starting with his plate approach, we're seeing his strikeout rate jump from 19.9% last season to 22.0% this season. His walk rate is also up, going from 4.8% to 6.1%. The jump in both rates is fairly negligible so I'm not worried about his strikeout rate increasing. It's good the walk rate is up, but it'd be awesome if it could get higher.

Looking at his batted ball profile is where things start to get a bit interesting. We're seeing virtually no change in his ground-ball rate with just a 0.1% jump to 42.9% this year. But the fly-ball rate is way down (40.0% to 33.0%). The good news is it's going straight to the line drive rate, jumping from 17.2% to 24.1%.

If we are going to see a decrease in flyballs then at least they're heading towards line drives. That's helped Rafaela hit as productively as he has this season.

We can see the benefit of all those line drives in Rafaela's .352 BABIP. More line drives usually means a higher average, but we have to question whether or not that number is too high. Last season he posted a .289 BABIP while he was up to a .312 BABIP in 2024. This is pointing towards negative regression.

Now to his Baseball Savant page to see how they view him and, unfortunately, there's quite a bit of blue here. His .352 wOBA is paired with a .304 xwOBA. That's quite the drop that's impossible to ignore.

What's backing those is a 38.4% hard-hit rate that's in the 35th percentile and an 8.3% barrel rate that's in the 51st percentile. The hard-hit rate is close to last season's number while the barrel rate is below what he posted last year. That added up to a .307 wOBA with a .305 xwOBA last year. It feels like we may be headed there.

As we look at the pitch mix it's a bit more straightforward than what we saw with Benge, though there's one pitch that's expecting some negative regression.

That would be the changeup. He's only seeing them 11.5% of the time and he's hitting them for a .397 wOBA. But that's paired with a .169 xwOBA. He's clearly getting very, very lucky against them.

He's been very strong against the four-seamer, though. He's hitting them for a .357 wOBA that's paired with a .365 xwOBA. He's been good against sinkers too, hitting them for a .382 wOBA that's paired with a .348 xwOBA. So fastballs aren't an issue for him.

His main weakness this season, and one that should stay that way, is sliders. He's hitting them for a .156 wOBA that's paired with a .187 xwOBA. If he doesn't get a pitcher's four-seamer early in the count then he's going to get a ton of sliders and that may not be a great scenario for him.

Verdict: The gap between wOBA and xwOBA are too large to ignore. Negative regression is clearly coming for him. I'm a fan of the high line drive rate he's posting, and that may make the drop not as steep, but negative regression is inevitable for Rafaela.

When all is said and done he should finish somewhere around last season's 98 OPS+. A league average mark isn't bad, but he's clearly overachieving and a drop in production is going to hit like a sack of bricks once this hot streak is over. If he's on your roster there's no need to drop him right now, but if you're looking to add him on your roster you may be able to find other options that carry less risk.

Jakob Marsee, OF, Miami Marlins

2026 Stats: .658 OPS, 89 OPS+, 3 HR, 14 RBI, 25 R, 13 SB

Another player featured last year in this article, Marsee has started to find his way out of his slow start. Though his OPS+ of 89 is a very underwhelming mark, that's jumped to a 176 OPS+ over the last two weeks.

Does that mean that we're back on the way to seeing Marsee reach his 134 OPS+ he posted last season? Or are we witnessing a fake out? You know the drill by now.

Jakob Marsee takes Jesse Scholtens deep for his third home run of the season.

Three-hit game for him, his second of the season.

As we look at his plate approach we're seeing that there have been fewer balls in play this season for the 24-year-old. His strikeout rate is up to 24.3% from last season's 20.5%. The walk rate has increased from 9.4% to 12.9%.

If you've read these articles before you know why a high walk rate is so important. It's helped him stay on base while going through a slump. It's also directly benefitting his ability to record stolen bases and runs. Look at those numbers! Those wouldn't happen if he wasn't getting on base as often as he is thanks to walks.

But there's still more to look at. So let's jump to his batted ball profile. We're seeing some pretty good changes here too as we see a massive decrease in ground-ball rate (44.4% to 30.0%) and a solid increase in fly-ball rate (35.2% to 48.3%). The line drive rate's just about the same, but it's almost always a good thing to hit the ball in the air more.

His BABIP is coming in at .277 this season, so we're probably expecting some positive regression here. Last season it was at an unsustainable .357, so we were expecting a lower number but this may be too low. So between this and the change in his batted ball profile you'd assume we're expecting some positive regression.

Baseball Savant seems to be projecting things differently, though. His current .305 wOBA is paired with a .295 xwOBA. That xwOBA is in the 25th percentile, well below his marks last season. So what gives?

It's likely a result of his low hard-hit rate (38.2%, 34th percentile) and a lower barrel rate (4.1%, 17th percentile). Even though he's been getting the ball in the air a lot more, he's clearly not hitting it as hard as he should be.

For what it's worth, his streak over the last two weeks has been the result of a 40.6% hard-hit rate and a 9.4% barrel rate. Those line up closer to last season's numbers so maybe we're starting to see the 2025 version of Marsee come back to life.

Jakob Marsee!

Looking at the pitch mix he faces we can see quite a jumbled mess of expected positive and negative regression. The only pitch that's getting true results is four-seamers. He's hit them for a .273 wOBA that's paired with a .267 xwOBA.

Sinkers (.278 wOBA, .318 xwOBA) and changeups (.328 wOBA, .367 xwOBA) are expecting positive regression. Sliders (.295 wOBA, .273 xwOBA), cutters (.366 wOBA, .302 xwOBA) and curves (.427 wOBA, .384 xwOBA) are all expecting negative regression. We've got a wide mix of floors here that project him has a good hitter, but not overwhelmingly powerful.

Verdict: I don't think I buy the negative regression that xwOBA is projecting here. There's too much of a positive difference in his batted ball profile that I think is going to start paying off a little more soon. Do I think he's going to be a world-beater? Not quite. But getting to an OPS+ closer to 105 or 110 is totally in play.

At 73% rostered in Yahoo! leagues there's only a slight chance he's on your waiver wire. Snag him if he's there. If he's on your roster then feel confident that the slow start is now in the past for Marsee. He's not a make-or-break type of player but he'll make for a solid complimentary piece to your lineup going forward.
