This announcement just came through from the Mariners:
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.
Right-handed pitcher Roy Corcoran was recalled from Triple-A Tacoma to take Putz's spot on the roster. Corcoran will be in uniform and available for tonight's game vs. the Washington Nationals.
Corcoran, 28, was 0-0 with a 1.69 ERA in eight relief appearances (10 2/3 innings) with Seattle earlier this season.
