Fantasy Baseball Sell-Highs: Early-Season Overachievers to Trade Away? (Week 13)

June 19, 2026

Joey's fantasy baseball sell-highs, overvalued players to consider trading away. These hitters and pitchers have overperformed early and may bust going forward.

Welcome back, RotoBallers, to another edition of early-season overachievers. Each week of the fantasy baseball season, we look at which star players might be sell-high candidates. Last week, we dove into players like Matt Chapman, Sandy Alcantara, and Geraldo Perdomo.

For this week, we'll analyze five more sell-high candidates. These five players should be moved in Week 13 of the fantasy baseball season, and each of them has overachieved this season. This list features a former National League MVP, a pitcher in the midst of a breakout season, and a veteran pitcher continuing to deliver quality starts.

Let's dive into the best sell-high candidates and overachievers in Week 13 of the fantasy season. All stats are through games on June 18.

Emerson Hancock, SP, Seattle Mariners

Seattle Mariners starting pitcher Emerson Hancock is in the midst of a career year on the mound. He currently owns a 3.28 ERA, a 1.017 WHIP, and 75 strikeouts across 79 2/3 innings pitched. His strikeout rate has jump 7.4% from 16.6% (2025) to 24% (2026), and his walk rate has dropped 2.7% from 8.1% (2025) to 5.4% (2026).

However, now is the perfect time to trade away Hancock. He is coming off his worst outing of the season, as he gave up a season-high six runs on nine hits with two strikeouts across four innings against the Nationals last weekend. That poor outing could be a sign of what's to come for the young right-hander because his metrics suggest some massive regression is headed his way.

His expected ERA (4.46) is 118 points higher than his actual ERA (3.28), and his expected batting average against (.255), average exit velocity (90.5 mph), chase rate (25.6%), barrel rate (10.7%), and hard-hit rate (44.7%) all rank in the bottom 35% of the league.

It's clear that Hancock is overperforming on the mound. Fantasy managers should expect his ERA to slowly decline, closer to his expected ERA. There's also a chance that the 27-year-old eventually moves to the bullpen, with the Mariners likely to promote top pitching prospect Kade Anderson at some point in the second half.

That all makes Hancock a massive sell-high candidate in Week 13.

Christian Yelich, OF/DH, Milwaukee Brewers

Milwaukee Brewers designated hitter Christian Yelich is heating up at the plate. He is batting .306 with one home run, four doubles, eight RBI, and two stolen bases across 14 games in the month of June. This hot stretch has Yelich slashing .275/.348/.431 with five home runs, nine doubles, one triple, and 24 RBI across 42 games this season.

Those numbers might look good on paper, but the lefty slugger is an easy sell candidate at this point in the season. His expected batting average (.231) is 44 points lower than his actual batting average (.275), and his expected slugging (.376) is 55 points lower than his actual slugging (.431). That's telling that Yelich is overperforming just a bit at the plate this year.

Add in the fact that he also has a bottom 40% xwOBA (.298), launch angle-sweet spot rate (29.7%), squared-up rate (19%), barrel rate (7.2%), and hard-hit rate (38.7%), and it's easy to see why he's a sell-high in fantasy baseball. His quality of contact is massively down, with significant decreases across several hitting metrics.

At 34 years old, Yelich is finally showing signs of slowing down. He is projected for just 16 home runs and 16 stolen bases this season.

Ceddanne Rafaela, 2B/OF, Boston Red Sox

Boston Red Sox outfielder Ceddanne Rafaela has posted solid all-around numbers in his fourth major league season. He is batting .287 with seven home runs, 30 runs scored, 16 doubles, two triples, 32 RBI, and seven stolen bases across 69 games in 2025. Rafaela has also been a steady fantasy contributor over the past month, as he's slashing .290/.317/.470 with 12 extra-base hits and 13 RBI since May 19.

The problem with Rafaela is that his metrics don't really match his actual numbers. The 25-year-old has a .296 xwOBA, .246 expected batting average, .366 expected slugging, 6.3% barrel rate, 36.3% hard-hit rate, 69.7 mph bat speed, and an 86.6 mph average exit velocity. All seven of those valuable metrics rank in the bottom half of the league.

That's enough reason to sell Rafaela in most leagues. He really isn't dominant in any one category, and his batting average should drop over the next few weeks, since his expected (.246) is 41 points lower than his actual (.287). With an 84-point difference between his expected slugging (.366) and actual slugging (.455) as well, there is some serious regression coming.

So, get rid of Rafaela before his numbers take a massive hit.

Justin Wrobleski, RP/SP, Los Angeles Dodgers

It's hard to deny how impressive Los Angeles Dodgers starting pitcher Justin Wrobleski has been this season. He has a 2.72 ERA, a 1.008 WHIP, and 50 strikeouts across 79 1/3 innings pitched. Wrobleski has been even more dominant on the mound as of late, as he has allowed one run or fewer in three of his last four starts.

The southpaw threw seven innings of one-run ball with a career-high nine strikeouts against the Phillies on May 29, threw six shutout innings with four strikeouts against the Diamondbacks on June 4, and recently threw six scoreless innings with five strikeouts against the Rays on Tuesday. His 1.90 ERA during this four-start stretch certainly has him trending up in Week 13 of the fantasy baseball season.

However, fantasy managers shouldn't expect these types of performances for much longer. The Dodgers left-hander has been one of the luckiest pitchers in baseball this season. His luck will eventually run out, which is why Wrobleski is one of the biggest pitcher sell-high candidates right now.

Wrobleski's expected ERA (4.16) is a whopping 144 points higher than his actual ERA (2.72). He also ranks in the bottom 20% of the league in expected batting average against (.267), average exit velocity (90.5 mph), whiff rate (17.7%), strikeout rate (15.8%), and hard-hit rate (44.4%). That poor strikeout rate, combined with his high hard-hit rate, is not a great recipe for success moving forward.

Wrobleski's numbers will eventually drop, so make sure to trade him away now while his fantasy value is high.

Sonny Gray, SP, Boston Red Sox

Boston Red Sox starting pitcher Sonny Gray has thrown the ball well this season. He has a 3.12 ERA and 55 strikeouts across 69 1/3 innings pitched. Gray has already notched eight wins in his first 13 starts and has allowed three earned runs or fewer in 12 of his 13 outings. These numbers have made the veteran a consistent fantasy option to start the year.

But Gray is a popular regression candidate over the next few weeks. His expected ERA (4.10) is 98 points higher than his actual ERA (3.12), and both his whiff rate (22.1%) and strikeout rate (19.9%) are massively down from a season ago. His swinging strike rate (9.5%) is also the lowest it has been since the 2022 season.

It's actually a bit surprising that Gray has such a low ERA despite his lack of swing and miss stuff. Last year, both his whiff rate (27.5%) and strikeout rate (26.7%) ranked in the top 30% of the league. This year, those two metrics rank in the 28th percentile and 33rd percentile, respectively. That's certainly a major concern.

Therefore, Gray should be dealt in Week 13 of the fantasy baseball season. He's overperforming on the mound and likely won't finish with a sub-3.40 ERA in 2026. This is the same pitcher who finished with a 3.84 ERA in 2024 and a 4.28 ERA in 2025 while posting elite strikeout numbers.
