MILWAUKEE -- St. Louis Cardinals left-hander Packy Naughton was placed on the 15-day injured list on Saturday because of a forearm strain.
Naughton was to have an MRI on Saturday.
Naughton, who turns 27 on April 16, faced three batters Friday in the eighth inning of a 4-0 loss at Milwaukee before the forearm issue caused him to leave.
The Cardinals recalled left-hander Génesis Cabrera from Triple-A Memphis to fill Naughton's spot on the roster.
Naughton has struck out five and allowed two hits and one walk in five innings of shutout relief this season. He went 0-2 with a 4.78 ERA and one save last season in 26 appearances, including three starts.
Cabrera was 4-2 with a 4.63 ERA in 39 relief appearances last season. He struck out 32 and walked 20 in 44⅔ innings.
