Adams battling back strain, hopes to avoid DL

PHILADELPHIA -- Phillies setup man Mike Adams has a "very mild" back strain and is day to day, general manager Ruben Amaro Jr. said Friday.

But Amaro said there was no urgency to place Adams on the disabled list because the team had had an extra reliever in the bullpen since last weekend. But the Phillies lose that extra reliever Tuesday, when they need a fifth starter. Amaro said if Adams could not pitch by Tuesday, the team might put him on the DL.

Adams, who received an MRI exam Friday, said his back still hurt on his right side whenever he twisted and that he did not want to rush to get back on the field and risk further injury.

"I'm still kind of hesitant to go out there and throw," said Adams, who has not pitched since May 10 against the D-backs. "I don't want to make it any worse than it needs to be. The main thing is to be smart about this right now; I don't know what the situation is. I was hoping by Sunday to be back out, but I really don't know now."

In 17 appearances this season, Adams is 1-3 with a 3.00 ERA, 19 strikeouts and six walks. When healthy, Adams is the Phillies' eighth-inning pitcher, a role manager Charlie Manuel said Antonio Bastardo would assume while Adams is unavailable.

Adams said he had not talked with the team about a possible trip to the disabled list. He mentioned he had incentive not to go on the DL because of his contract. If Adams makes a combined 120 appearances in 2013-14, he would be guaranteed a $6.5 million option in 2015 if his arm is healthy entering 2015.
