The Miami Marlins placed right-hander Sandy Alcantara and outfielder Jorge Soler on the injured list Wednesday.
Alcantara went on the 15-day IL with a right forearm flexor strain, while Soler went on the 10-day IL with a right oblique strain.
Alcantara, 28 on Thursday, allowed four runs (two earned) in eight innings in a 6-4 victory over the Washington Nationals on Sunday. The reigning National League Cy Young Award recipient has permitted 15 runs (13 earned) in his last four starts (26 1/3 innings).
The two-time All-Star is 7-12 with a 4.14 ERA in 28 games (all starts) this season.
Soler, 31, made his first All-Star team this season and is batting .240 with 35 homers and 71 RBIs in 126 games.
The Marlins also called up outfielder Dane Myers, right-hander Edward Cabrera and left-hander Devin Smeltzer from Triple-A Jacksonville. Right-hander Geoff Hartlieb was designated for assignment.
