Analyzing Every Boston Red Sox Rounds 6-10 Draft Pick In 2026 MLB Draft

The Boston Red Sox did not make a crazy splash in day one of the 2026 MLB Draft, going under-slot with Jake Schaffner or right on it with Owen Hull and Jace Mataczynski. It was off-brand seeing the Red Sox prioritize the offensive side of things after the first two drafts under Breslow's tenure being incredibly pitcher focused.

We now see a shift back to the norm in Rounds 6-10, as they attacked high-extension pitchers while making a huge splash in the ninth round, selecting a prep prospect we at DiamondCentric had in the top 100 of our consensus mock draft board. Below you can find more analysis on the players selected in rounds 6-10 of the draft on Sunday. 

Round 6: Brett Lanman, LHP, Abilene Christian University

Lanman fits the typical Red Sox desired pitcher build, standing at 6'5 and getting good extension off the mound. However, his numbers in his junior season won't jump out with a 5.35 ERA and a 1.40 WHIP. His 24.1% strikeout rate was sixth in the Western Athletic Conference and first on ACU, but he'll need to work on reducing his walk rate to have a chance at impacting the major leagues. According to Baseball America, Lanman sits in the low 90s with his fast and will occasionally touch 95, while also mixing in a cutter/slider, a changeup, and the occasional curveball. Lanman is a clear project pitcher for the Red Sox, but they have been able to thrive developing pitchers with his physical traits.

Round 7: Kide Adetuyi LHP, Florida Atlantic University

Once again, the Red Sox select a collegiate left-handed pitcher that can generate elite extension. Adetuyi stands much shorter than the aforementioned Lanman at only 6'1, but he still can get almost seven feet down the mound despite some perceived physical limitations. Adetuyi pitched 73 innings last season with a 4.19 ERA and a 1.27 WHIP. His 27.5% K% was third in the American Athletic Conference and led the Owls. Baseball America describes his motion as a "low slot" with some "funk and crossfire" and he comes with a filthy sweeper that generates 2700 RPMs with almost a foot of glove-side movement. Adetuyi was ranked 442nd on Baseball America's big board.

Round 8: Josh Volmerding, LHP, California Polytechnic State University

Similarly to Red Sox sixth-round pick Brett Lanman, Volmerding stands at 6'4, 200 lbs. He pitched to the tune of a 6.51 ERA with a 1.55 WHIP. He gets up to 95 mph on his fastball and in 2026 he set a new career-high in strikeout rate, getting to 24.2% in 27.2 innings of work. His FIP was significantly lower than his ERA at 3.89. It's also worth noting he dealt with a knee issue this season, which cut his year short. 

Round 9: Martin Shelar, OF, Marist HS (GA)

Finally, the Red Sox show us where all the slot money was headed. Martin Shelar is a significantly over-slot selection by the Red Sox, projected 71st on our consensus mock board while being selected 274th.

Our Jamie Cameron says of the selection: "Shelar is a prep outfielder out of Georgia with some of the best athleticism in the class. It's likely he commands a big bonus in July. If it's not met, he's currently committed to Mississippi State. Shelar's swing divides opinions — it can get steep at times, with a two stage stride that may have to be tweaked as a pro, but there's no denying the results. This is some of the best bat speed and raw power on the prep side in 2026, and despite the unconventional swing, he continues to find the barrel plenty, alleviating concerns around his hit tool. There's good speed and an above-average arm in this profile too, so Shelar has more value to add than simply raw pop. He's a prototypical (compliment) high school corner outfield prospect with a shot at becoming a 25-25 player as a pro if it all clicks." 

One has to assume the Red Sox and Shelar are in agreement on the financial side of things. Deals have rarely fallen through this early in the draft in recent years. This is a huge splash for Boston and one that fans should be seriously excited about.

Round 10: Kaleb LaFavor, RHP, Bishop Heelan HS (IA)

Yet again another giant at pitcher, this time in the form of 6-foot-6 Kaleb LaFavor. According to Baseball America, LaFavor sits in the low-90s with his fastball and occasionally touches 95, but given his height and frame, his velocity could spike as he continues to mature. He also possesses a slider, changeup and mixes in the occasional cutter. LaFavor is currently committed to Iowa.
