Squanders save chance
Weissert (4-4) took the loss and blew a save during Sunday's game against Miami, allowing two runs on two hits with no strikeouts over one-third of an inning.
Analysis
The Red Sox called upon Weissert in the ninth inning Sunday, as closer Aroldis Chapman got the day off after pitching in back-to-back games. Weissert inherited a one-run lead, but he surrendered a leadoff homer to Dane Myers on his second pitch of the inning. The 30-year-old reliever departed the contest with a runner on first in favor of Steven Matz, who yielded a go-ahead two-run homer to the first batter he faced. Weissert has now blown seven of his 10 save chances, and he yielded multiple runs in an outing Sunday for the first time since July 2.

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).

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.
