Chris Welsh elevated Jack Leiter's fantasy profile, citing two consecutive strong starts where Leiter displayed improved command, a solid slider, and an outstanding fastball. While Welsh doesn't yet consider Leiter a 'must-grab', he's no longer just a casual streamer. Welsh recommended Leiter as someone worth picking up and holding in competitive leagues due to the visible improvements and potential established upside.

Chris Welsh highlighted Jack Leiter as an intriguing buy-low waiver wire pickup if he becomes available due to concerns over his blister issue. Though Leiter is already rostered at a 71% rate, managers might panic-drop him to free up roster space. Welsh advised closely monitoring waiver wires for Leiter, as blister injuries often scare away fantasy managers despite typically short-term impacts. Given Leiter's talent and upside, picking him up with even a slight discount could yield significant returns later this season.

Dan Plesac believes Jack Leiter has a legitimate shot at winning AL Rookie of the Year. Leiter impressed this spring by adding a quality straight change-up to his repertoire, complementing his existing arsenal. Plesac emphasized Leiter's strong baseball lineage and South Jersey pitching heritage as contributing factors, asserting this is the season Leiter fully breaks out and reaches his potential.

Dana Lane recommended betting against Jack Leiter in his season debut against the Red Sox. Lane highlighted concerns around Leiter's limited MLB experience, noting he has yet to earn his first MLB win, posting three losses in six starts last year. Leiter had an average spring training, and Lane expressed doubts about his readiness and the heavy expectations placed on the young pitcher to anchor the rotation of a team aspiring toward a deep playoff run. Lane expects Boston to capitalize on Leiter's early-season uncertainty and projected struggles.

Eric Lindquist raises serious concerns about Jack Leiter's upcoming performance. He specifically highlights Leiter's concerning statistics from last season, citing an alarmingly high .507 expected slugging, a .376 expected wOBA, and a substantial 44.6% hard hit rate combined with a lofty 16.4-degree launch angle. He also points out that the Texas environment played hitter-friendly with Arlington's roof open recently, leading to more home runs. With Leiter displaying major contact issues, Lindquist strongly suggests fading him or targeting offensive success by opposing hitters.
