Amaro: Rollins is better

Jimmy Rollins was feeling better Thursday, Phillies general manager Ruben Amaro Jr. said, after the shortstop left Wednesday's game with tightness in his right hamstring.

The GM said Rollins remains day-to-day.

Rollins injured his hamstring running from first to second on a two-out double in the third inning Wednesday. He was replaced by Wilson Valdez.

After the game, Charlie Manuel said Rollins had been sick and did not take batting practice. Other players, including catcher Paul Hoover, had also been ill, Manuel said.

The manager was told dehydration from the sickness could have led to the tight hamstring. Rollins was not available for comment.

"Our trainer and the doctor, they felt like he was going to be OK," Manuel said. "That's kind of the impression they gave me."

Rollins, who has already missed 59 games this season due to a right calf strain and bruised left foot, was visibly upset upon entering the dugout after scoring a run in the third. He sat on the bench with his head down talking to head athletic trainer Scott Sheridan. A few seconds later, he stood up, ripped off his skull cap and headed down the tunnel back to the clubhouse.

The Phillies are obviously optimistic about Rollins based upon roster moves made Thursday. Lefthander Nate Robertson, who was tagged for six runs in Wednesday's game, was designated for assignment. But an infielder -- as insurance for Rollins -- was not added.

Instead, the Phillies claimed righthander Cesar Carrillo off waivers from the Padres. Carrillo, 26, went 5-14 with a 5.60 ERA in 27 starts for triple-A Portland this season. Carrillo was not added to the active roster.

In addition, righthander Scott Mathieson was placed on the disabled list Thursday with a strained back muscle. Mathieson said Wednesday he was stiff but that he would be fine. Apparently that changed overnight.
