The Diamondbacks rotation is in flux. This has been brought on by a combination of factors, including injury to Luke Weaver, and previous poor performance by Zack Godley, opening up two spots in the rotation.
Those spots have been filled by Taylor Clarke and Jon Duplantier, with sub optimal results in terms of team W-L as well. In fact, just looking at the 16 games started by these three, the team is 6-10 in those games.
All three of them have successful relief innings as well, but the table below is only looking at their efforts as starting pitchers.
