Weissert pitched a scoreless ninth inning during which he allowed one hit in the 5-0 win over the Blue Jays on Monday.
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.
