SEATTLE — The Seattle Mariners have placed closer J.J. Putz on the 15-day disabled list with a hyperextended pitching elbow.

Putz already has missed 18 games with a rib cage injury and also has had knee and finger pain. The right-hander was removed from Wednesday's win at Toronto in the ninth inning after shaking his arm following a pitch.

Putz had an MRI exam Thursday. The 31-year-old has a 5.21 ERA with 17 walks and three blown saves in 20 games this season.

Putz made the All-Star team in 2007, finishing with 40 saves and a 1.38 ERA.
