Mariners’ Austin Adams Will Require ACL Surgery

Mariners right-hander Austin Adams will need surgery to repair the torn ACL and meniscus in his right knee, according to Greg Johns of It’s devastating news for the 28-year-old Adams, who now faces an approximate 6-8 month recovery timeline.

The injury diagnosis comes after Adams underwent an MRI Sunday morning, which was precipitated by Adams’s departure from last night’s game after suffering a knee injury while covering first base.

Adams has been one of the bright spots of the Mariners lackluster season, at times looking dominant out of the bullpen. He’s ridden a dynamic slider to a solid 53:16 K:BB ratio in 32 innings between the Nationals and M’s this year, good for a 14.9 K/9. As Johns notes in a later Tweet, that’s a mark that ranks among the best by a reliever in Mariners history (minimum 100 batters faced).

While that doesn’t mean that Adams was flawless, he has nonetheless proven to be a fine discovery by the M’s front office and a piece that could factor into future Seattle bullpens. For a year in which the M’s have trotted out dozens of fringe relievers, Adams has been one of the definite successes after he was acquired from Washington in May.

However, those plans will have to be temporarily put on hold as Adams will now have to work his way back from a significant knee injury. His recovery will no doubt cut into his 2020 season, with the upper estimate for recovery placing him on track to be at full health in late May, though he likely wouldn’t be able to return to game action until about midseason.
