Red Sox Injury Updates: Yoshida's Injury Significant, Whitlock & Slaten Updates

The Boston Red Sox received some injury updates Tuesday afternoon before the second game of their three-game series against the Arizona Diamondbacks. Following the injuries to outfielder Masataka Yoshida and pitchers Garrett Whitlock and Justin Slaten, the three were scheduled for MRIs. Only two of them came back positive. 

As first reported by MassLive's Chris Cotillo, both Whitlock and Slaten received good news as there was no structural damage, just inflammation, found in both of their MRIs. The two key pitchers of the Red Sox bullpen will remain shut down for now with the length of their downtime unknown. 

Yoshida, on the other hand, received tough news as his injury turned out to be significant with there being a chance he misses the remainder of the regular season. The loss of Yoshida's bat is a major blow to the Red Sox as they look to make it back to the postseason. In his last 22 games, the outfielder was hitting .292/.361/.403 with five doubles, one home run and 10 RBIs. 

The Red Sox also gave an update on Tanner Houck, stating that he threw a live bullpen session in Fort Myers and that it is now possible he could return this season. The right-hander underwent Tommy John surgery on August 18, 2025.
