ST. PETERSBURG, Fla., July 26 (UPI) -- The New York Yankees placed All-Star closer Mariano Rivera on the 15-day disabled list Friday with a mild strain in his right shoulder.
Rivera was placed on the disabled list retroactive to Saturday, when he left a game against the Boston Red Sox due to stiffness in his right shoulder. It is the second stint on the DL this season for Rivera, who was sidelined by a strained groin in June.
The Panamanian righthander has struggled of late, allowing seven runs and seven hits in his last four appearances. He is 1-4 with 24 saves and a 3.06 ERA in 35 appearances.
The 32-year-old Rivera is the Yankees all-time leader in saves with 239. He set a club record with 50 saves in 2001 and has averaged 42 over the last five seasons.
The Yankees recalled pitcher Randy Choate from Class AAA Columbus to take Rivera's place on the active roster.
Choate joined the Yankees on April 21 and made 17 relief appearances before being optioned to Columbus on June 28. He has a 6.33 ERA this season, allowing 15 earned runs in 21 1/3 innings.
The 26-year-old lefthander is 3-2 with a 4.36 ERA in 76 career relief appearances with New York since 2000.
Choate was 2-2 with one save with and a 3.97 ERA in 15 appearances at Columbus, including one start.
