MIAMI -- Marlins reliever A.J. Ramos was placed on the 15-day disabled list with right shoulder inflammation following the Marlins' 5-4 win in 11 innings over the Phillies on Tuesday night at Marlins Park.
Ramos, who threw a career-high 50 pitches in 1 2/3 innings in the Marlins' 14-inning loss to the Phillies last Thursday, underwent an MRI that revealed the inflammation on Friday. He did not pitch in the series against Oakland in hopes that extended rest would relieve the soreness.
Ramos' stint is retroactive to June 27. A corresponding roster move will be announced on Wednesday. The team is expected to bring up a position player, and the likely choice is Justin Bour, who was not in Triple-A New Orleans' lineup on Tuesday.
The past few days the Marlins have been carrying 13 pitchers and 12 position players. Bour is a first baseman and a left-handed hitting option off the bench.
Ramos tested his arm on Tuesday, long-toss throwing for the first time since his outing at Philadelphia. Although he felt considerably better than in recent days, the Marlins are taking no chances.
Ramos and Mike Dunn lead the Marlins' relievers in appearances with 39.
Prior to the 50 pitches he threw at Philadelphia, Ramos' high pitch count was 33 in one inning on June 15.
"It's a little sore. Nothing more than inflammation," Ramos said. "As a precaution, we want to make sure everything is alright."
The bullpen will miss Ramos while he's out. He's become vital in late innings, racking up 12 holds, a 4-0 record and a 2.17 ERA. In June alone, he posted a 0.64 ERA in 14 frames, making him one of the most effective Miami relievers during that month. Only Bryan Morris' 0.00 ERA in 16 2/3 innings was better.
The Marlins hope to rely on Morris and righty Kevin Gregg, their most experienced reliever, to pick up Ramos' slack. Gregg, however, allowed the Phillies to tie the game Tuesday and was tagged with a blown save after allowing back-to-back home runs in the eighth inning. He was lifted for Dunn, who recorded the final out of the inning.
