Starting Pitcher Fantasy Baseball Breakouts or Fake Outs? Pitchers On The Rise (Week 10)

June 4, 2026

Are these pitchers fantasy baseball breakouts or fake outs? Dan analyzes advanced pitcher statistics and surging fantasy baseball SPs for Week 10 of 2026, including

Welcome back to another edition of my weekly starting pitching column. As usual, I'll take a closer look at three starting pitchers and attempt to yield a verdict about the sustainability of their current production. This week, I'll investigate the breakout of Pirates second-year pitcher Braxton Ashcraft, the impressive return of Mariners' fireballer Bryce Miller, and the first few starts from Athletics' lefty Gage Jump.

If you are new to this column, remember that the goal is to look at several pitchers each week who are showing signs of "breaking out." That term gets thrown around a lot in our industry, but to me, it means they're flirting with the possibility of improving their baseline performance across a larger sample.

So, while we typically look at younger pitchers as potential "breakouts," I won't limit myself to only youngsters. The concept of the breakout can be applied to pitchers of all experience levels, as we have seen numerous examples of pitchers improving significantly from season to season, even into their 30s. All roster percentages are courtesy of Yahoo! Let's see which of these arms we can trust going forward and where we can expect regression! All statistics were current through Wednesday, June 3.

Braxton Ashcraft, Pittsburgh Pirates

• 85% Rostered
• 2025 stats: 69.2 IP, 2.71 ERA, 1.25 WHIP, 24.3% K%, 8.2% BB%
• 2026 stats: 74.2 IP, 2.77 ERA, 1.03 WHIP, 27.3% K%, 5.7% BB%

The Ashcraft breakout has been a thing of beauty for me in more ways than one. First of all, I am a Pirates fan, and so I get the satisfaction of watching him pitch incredibly well for my team. And secondly, he was one of my top value picks in the preseason. I touted him pretty hard and ended up with him on a bunch of teams.

But no, this is not one big victory lap, I promise. I picked him this week because after his last dominant outing (6 IP, 2 ER, 11 K) against the Twins, he's put himself in the conversation as a top 15 pitcher in MLB. Right now, he ranks 59th overall on Yahoo's player rater with five wins and 81 strikeouts across 74.1 innings.

There were some questions as to whether he could build upon his successful rookie season, since he worked out of the bullpen in addition to making some starts. But Ashcraft has not only been dynamic as a strikeout artist and run suppressor, but he's also eating innings as he ranks 11th in MLB in innings pitched. All but two of the pitchers ahead of him have made a 13th start, too, while Ashcraft will make his in a few days.

The arsenal is quite balanced across his four main pitches. He did up his four-seamer usage this season, while throwing fewer sliders. The curveball is still his best swing-and-miss pitch with a 41.9% Whiff%. But his hard slider (average velocity of 92 mph) has a 34.9% Whiff%, too.

Having two different breaking balls with very different shapes and velocities to go with his four-seamer and sinker that both sit around 97 mph makes it incredibly tough on hitters.

Even though his sinker is utilized somewhat sparingly, it has very good horizontal and vertical movement. He gets his share of groundballs (47%) and is limiting hard contact in a big way (5.7% Barrel%, 2.77 xERA).

The control from Ashcraft has been elite as well. His 5.7% BB% is backed by a silly low 30.8% Ball%. The strikeout rate (27.3%) is backed by a strong 13.7% SwStr%, too, so his fantastic K-BB% of 21.6 looks pretty darn sustainable to me.

He's literally checking every box here. The only concern we might have is that he's quickly approaching how many innings he pitched last year between Triple-A and the majors (118). If the Pirates do decide to have him skip starts or put him on a pitch count, it could limit his upside. But right now, he looks like one of the best picks in fantasy baseball drafts and is showing no signs of slowing down.

Verdict: You can always consider selling high, but personally, I'd just enjoy the high-end production and pat yourself on the back for drafting him (or snagging him off waivers).

Bryce Miller, Seattle Mariners

• 51% Rostered
• 2025 stats: 90.1 IP, 5.68 ERA, 1.41 WHIP, 18.9% K%, 8.7% BB%
• 2026 stats: 21 IP, 1.71 ERA, 0.86 WHIP, 25.3% K%, 3.8% BB%

Is Bryce Miller officially back? After a really strong 2024 campaign in which he won 12 games and logged 180 innings with a 2.94 ERA, he struggled mightily last season while dealing with injuries. He was looking good in spring training before experiencing an oblique injury that delayed his start to the season until mid-May.

He's been fantastic through his first three starts of the 2026 season, showing off above-average strikeout stuff and the type of elite control (3.8% BB%) that was his calling card in his first two big league seasons.

Most notably, the velocity on his four-seamer is back up to 96.7 mph after dipping to 94.8 mph last season. That extra two mph on the heater makes a big difference, especially when Miller has elite iVB (19 inches) on the pitch.

The location of his four-seamers (and other pitches) is also much improved as he's sporting an 111 Location+ rating thus far. Miller's Stuff+ rating of 112 is also a career best and likely reflects the improvement to his fastball as well as an increase in slider usage this season. His arsenal is mainly four-seamer, splitter, slider, but he also mixes in a cutter, sweeper, and curveball.

Miller's splitter continues to be effective, but the slider has been filthy with a 48% Whiff%, ten percentage points better than it was last year. The key is really the fastball and the location, which is what sets the table for everything else. But it's great to see him lean into the slider usage and also continue to experiment with other offspeed pitches as well.

Miller's 13.4% SwStr% would be a career high if it sticks, and the batted ball data looks great, too (3.6% Barrel%, 1.93 xERA). The only thing you can point to for possible regression would be a 92% strand rate, but we're getting pretty picky if that's the only red flag.

Verdict: It all boils down to staying healthy for Miller. He looks like the best version of himself so far (small sample size warning), and a guy who could be a real difference-maker in fantasy leagues. Proceed with cautious optimism - stay healthy, Bryce!

Gage Jump, Athletics

• 13% Rostered
• 2026 Triple-A stats: 38 IP, 4.50 ERA, 1.47 WHIP, 33.1% K%, 11.8% BB%
• 2026 stats: 12 IP, 3.75 ERA, 1.17 WHIP, 20.4% K%, 4.1% BB%

It's always tough trying to analyze a pitcher who has only made a few major league starts, but I'm going to do it anyway. Because now is the time to be proactive and add Jump off the wire. If you wait for another good outing, he's going to get scooped up in your league; it's that simple.

So why is Jump worth an add? Well, truth be told, his numbers don't "jump" off the page (sorry, I know, but I had to). He had a 33% K% in the minors this year, but has struck out just 20% of MLB hitters with a 9.2% SwStr%. So the strikeouts aren't there yet, but he has shown very good control (4.1% BB%) and gotten some good batted ball results (3.11 xERA) even while sporting a .343 BABIP.

The young lefty has some juice on his fastball, averaging 96.4 mph on his heater. That will certainly get some attention as a left-hander, and it's a pretty good fastball with a solid 17 inches of iVB. He's leading with the four-seamer 50% of the time and utilizing his slider around 25% of the time, while mixing in a curveball, changeup, and sweeper.

Jump throws from a pretty high arm slot, but still gets really good horizontal movement on his slider. His curveball has excellent downward bite, while the changeup comes in at 89 mph and acts as a nice change-of-pace pitch to righties.

Interestingly, Jump got the call-up so quickly. He had a 4.50 ERA at Triple-A and only one year of minor league experience before this year. But we have seen some of these very good college pitchers come up quickly and adapt on the fly with success (Skenes and Burns come to mind), so it's not to say that he can't do it.

Ideally, we'd like to see more strikeouts from the hard-throwing southpaw. But I think his first two starts have to be viewed as an overall success, and there's certainly plenty of room for growth. I'm not ready to call him a full-fledged breakout just yet, but there's enough potential here to get excited.

Verdict: Jump has the arsenal to have success at the MLB level. We'll certainly need to see him pitch well over a larger sample to feel more confident, but investing in him now - while he's still so widely available - makes a lot of sense.
