Diamondbacks Lose All-Star To Injured List

The Arizona Diamondbacks made a point of going out and adding some depth to their bullpen this offseason. Turns out that's coming in handy even before Opening Day, as they've now lost their best reliever to start the season, in Joe Mantiply.

There's no indication that this is anything serious, as Mantiply is suffering from shoulder fatigue. The D-Backs are providing no other details at this point.

The 5th-year reliever followed up a nice 2021 with an All-Star season in 2022. He was easily the Snakes' most reliable reliever, tossing 60 innings with a 2.85 ERA and a tremendous 61:6 strikeout-to-walk ratio. He's improved his strikeout rate and walk rate in each of the last three seasons. 

Arizona had brought in relievers Scott McGough, Miguel Castro,  and Cole Sulser this offseason, and it appears that McGough will start the season as the closer.
