Even though righthander B.J. Rosenberg was called up three times last year by the Phillies, he was surprised that it happened on Friday.

The Phillies recalled Rosenberg from triple-A Lehigh Valley and optioned lefthander Raul Valdes to the IronPigs. Valdes had a 7.65 ERA in 10 relief appearances this season.

"I was kind of shocked," Rosenberg said before Friday's game with the Cincinnati Reds at Citizens Bank Park. "I really wasn't expecting anything, but obviously am very excited to get the opportunity."

Rosenberg, who turns 28 in September, was used as a starter this season for the IronPigs.

"With starting, I wasn't expecting to get called to pitch in the bullpen," said Rosenberg, who was 1-3 with a 4.30 ERA in seven starts this season at Lehigh Valley.

His most recent start was his best. On May 12, Rosenberg pitched seven shutout innings, allowing four hits in a 6-4 win over Durham.

Last season Rosenberg pitched for Reading, Lehigh Valley and the three stints with the Phillies. In 22 games for the Phillies he was 1-2 with a 6.12 ERA.

Yet Rosenberg finished the season strong. In nine appearances in September/October, he was 1-0 with a 1.26 ERA in 141/3 innings.

"That experience from last year definitely helped, especially how I pitched toward the end of the year," Rosenberg said. "That helped my confidence and will help me this year."

Adams day-to-day

Mike Adams said he wanted peace of mind, which is why he underwent an MRI on his back on Friday.

Adams didn't know the results when he talked to the media before the game, but general manager Ruben Amaro Jr. later told reporters that it was a mild mid-back strain and said Adams is day-to-day.

Adams hurt the back on Sunday in Arizona, shagging a fly ball during batting practice before the Phillies' 4-2 extra-inning win over the Diamondbacks.

"If I twist on the right side is when I feel it," Adams said. "Everything else is normal, and I can lift my kids up and feel nothing."

Adams is 1-3 with a 3.00 ERA in 17 games, with 19 strikeouts and six walks. Opponents are hitting .240 against him.

Streaking Kendrick

Kyle Kendrick opposes Cincinnati's Bronson Arroyo in Saturday's middle game of the series. Kendrick (4-1, 2.47 ERA) has allowed two earned runs or fewer in seven consecutive starts.

Arroyo hasn't had the greatest success against the Phillies at Citizens Bank Park, where he is 1-2 with a 9.60 ERA in three games.
