Rest-of-Season Projections
Signed a one-year contract with the Red Sox in March of 2026.
Scoreless inning in win
Weissert pitched a scoreless ninth inning during which he allowed one hit in the 5-0 win over the Blue Jays on Monday.
Analysis
Weissert has tallied 62 or more appearances the last two seasons with the Red Sox and is on pace for that again with 13 trips to the mound over Boston's first 29 games. The right-hander is being used primarily low-leverage situations thus far after blowing nine save opportunities last season, the second most in MLB. Weissert does continue to boast above-average swing-and-miss stuff, however, recording 16 strikeouts across his first 11.2 innings in 2026.

Past Fantasy Outlooks
2024
2023
Weissert has yet to break through in high-leverage at the big league level, but he may be in line for more late-game opportunities after an offseason trade from the Yankees to the Red Sox. The 29-year-old has racked up 51 saves in the minors since 2016, but his strikeout prowess has yet to translate in the majors with a near league average strikeout rate through 31.1 career innings. Weissert slightly improved his walk rate in his limited sample last year, but if he continues making strides with his control during spring training, he'll have a much better shot of breaking camp with the Red Sox. The right-hander's chances of entering Boston's high-leverage mix will only increase if the team elects to trade its veteran relievers on expiring contracts (Kenley Jansen and Chris Martin).

Latest Fantasy Rumors
Remains in plans
According to Marly Rivera of ESPN.com, manager Aaron Boone said Tuesday that Weissert is "a big leaguer" and "will be an important part of this team" despite missing the Opening Day roster.
Analysis
The 28-year-old was optioned to Triple-A Scranton/Wilkes-Barre, but it should only be a matter of time before he rejoins the major-league club. Weissert had a 5.56 ERA, 0.97 WHIP and 11:5 K:BB over 11.1 frames in his first taste of the big leagues last season, and he was dominant at Triple-A with a 1.69 ERA and 36.8 percent strikeout rate.
