The Philadelphia Phillies placed left-hander Jose Alvarado on the 15-day injured list Wednesday with inflammation in his pitching elbow.
Alvarado initially felt discomfort during warmups ahead of Tuesday's 8-4 win over the Toronto Blue Jays. The IL move is retroactive to Monday.
The 27-year-old reliever has converted five of seven save chances this season, compiling a 1.88 ERA with 24 strikeouts and zero walks through 14⅓ innings.
The Phillies reinstated right-hander Andrew Bellatti from the injured list in a corresponding move. Bellatti threw two scoreless innings in two rehab appearances at Single-A Clearwater while recovering from right triceps tendinitis.
Bellatti, 31, was 1-0 with a 6.23 ERA in 10 relief appearances with the Phillies before his injury.
