BOSTON -- Red Sox reliever Bobby Jenks said Friday an MRI confirmed that he is suffering from tendinitis and a strained right biceps.
The right-hander, who signed a two-year, $12 million contract with the Red Sox as a free agent over the winter, was placed on the disabled list Thursday because of the arm trouble.
Jenks, who has been generally awful this season (1-2, 9.35 earned-run average with 13 hits and nine earned runs allowed in only 8 2/3 innings) said he was trying to throw through the injury for more than a week. His arm cramped after he warmed up during Wednesday’s marathon 13-inning game, rendering him unavailable for that game.
Friday he described how his arm was feeling a few days ago.
“Standing here doing nothing it felt like I had just done 12 sets of [weight-lifting] curls,” said Jenks. “It was fatigued. [There was] achiness.”
Rest has been prescribed. Jenks said he is supposed to go three or four days without picking up a baseball. He said that after a day and a half of rest, his arm already feels as if it has loosened up.
“We caught it in time,” said Jenks, who added that his elbow, which had caused him problems last year, is feeling fine.
Jenks is hoping that he will be ready to return when his 15 days on the disabled list is up. For the next few days his work in the weight room will be confined to cardio and leg work.
