Adams 'excited' to be back with Phils' bullpen

WASHINGTON -- As expected, the Phillies activated relief pitcher Mike Adams off the 15-day disabled list Sunday morning, ahead of their afternoon game against the Nationals. The club had optioned fellow right-hander B.J. Rosenberg to Triple-A Lehigh Valley after Saturday night's contest to open a spot on the 25-man roster.

Adams last pitched on May 10, and he was placed on the DL with a strained back. Sunday was the first day he was eligible to be activated.

"It's good," Adams said of the back issue. "It lasted about four or five days of actual pain, and after that, it was gone. The past week, it's been more of getting the arm back in throwing shape. You take a week off throwing, it takes a toll on you, not throwing for such a long time. But everything's good to go now, and I'm excited about getting back out there."

Adams threw a bullpen session on Wednesday at Marlins Park when the Phillies were in Miami. At that point, the team did not expect him back until this coming Tuesday or Wednesday.

But the 34-year-old threw another bullpen session on Friday in Clearwater, Fla., and felt good enough afterward to skip a rehab appearance at Class A Clearwater that had been scheduled for Monday.

Adams is 1-3 with a 3.00 ERA in 17 appearances this season, his first with the Phillies. He has struck out 19 and walked six over 15 innings.

Rosenberg was 0-0 with a 12.00 ERA in three innings over three appearances for the Phillies this season.
