Justin Slaten: Breaking News

The Red Sox placed Slaten on the 15-day injured list Wednesday due to a right oblique strain. Boston had previously noted that Slaten wasn't available out of the bullpen for Tuesday's 3-2 win over Milwaukee due to a sore oblique, but the righty reliever will now be shut down for at least two weeks after being diagnosed with a strain. The Red Sox recalled lefty Tyler Samaniego from Triple-A Worcester to take Slaten's spot in the bullpen. For his part, Slaten believes his injury is minor and is hopeful to return from the IL when first eligible April 20, per Jen McCaffrey of The Athletic.

Slaten was unavailable for Tuesday's game against the Brewers due to oblique soreness, Chris Cotillo of MassLive.com reports. The team has labeled Slaten as day-to-day, so his injury doesn't seem to be too severe. The 28-year-old is off to a strong start this season after striking out five batters over 3.1 shutout innings, picking up holds in two of his four appearances.

Slaten struck out one over one scoreless inning to earn a hold in Friday's 5-2 win over San Diego. Slaten pitched a 1-2-3 eighth inning to earn his second hold in three appearances this season, both of which set up saves for closer Aroldis Chapman. Coming off a 2025 season impacted by a shoulder injury, a healthy Slaten will be a vital piece of the bullpen's setup crew in 2026.
