Christian Bethancourt exited Tuesday's game against the Braves with a left intercostal strain.
That's typically a four-week injury for a position player. Bethancourt was 0-for-2 before exiting and is batting just .228/.265/.368 in 73 games this season.
Zack Godley has been moved to the bullpen.
That's how the Diamondbacks will clear a spot for Shelby Miller, who is set to return to the rotation Wednesday against the Giants. Godley, 26, has a 6.71 ERA and 1.51 WHIP in nine starts and seven relief appearances this season at the major league level.
Dodgers recalled RHP Casey Fien from Triple-A Oklahoma City.
Fien had a 3.80 ERA, 1.14 WHIP, and 20/6 K/BB ratio in 23 2/3 innings earlier this season out of the Los Angeles bullpen. He'll return to a middle relief role.
Dodgers optioned RHP Pedro Baez to Double-A Tulsa.
Baez will be back when Tulsa's season comes to a close later this week. The right-hander owns a 3.61 ERA in 62 1/3 innings this year out of the Dodgers' bullpen.
Homer Bailey (biceps) will not take his next turn in the Reds' rotation.
But the hope is he won't be out much longer than that. Bailey allowed four runs on five hits in just one inning of work Sunday against the Diamondbacks and was diagnosed later that day with right biceps tendinitis. He has a 6.65 ERA through six starts in his return from Tommy John reconstructive elbow surgery.
