Amaro stressed that Lidge has had no discomfort in his shoulder.
"He was shut down for a couple of days just to let [the elbow] cool off," Amaro said. "Throwing long toss, he was fine, and then when he got back on the mound he felt this discomfort again."
Lidge missed 37 games and had two stints on the DL last season with elbow problems.
Amaro said an MRI exam on Jimmy Rollins' right knee Monday showed no damage. The shortstop was walking with a slight limp in the clubhouse before sitting out his second straight game. Rollins will return to the lineup when the soreness dissipates and the swelling goes down.
Rollins wrote on his Twitter account that he's "Feeling a lot better & will continue to get treatment on it. Looks good though."
Rollins fouled a ball off his right knee in the first inning Saturday at Pittsburgh and left the game after a couple of innings.
Brown vs. lefty
Domonic Brown made his first start this season against a lefthander, the Dodgers' Ted Lilly. Leftfielder Raul Ibanez was rested.
Charlie Manuel said it was a good time to test Brown against a lefty because Lilly throws with an overhand motion.
"I thought it's a good time to get Raul off his feet and give him a blow," Manuel said. "I also like Domonic playing against Lilly. He's more of a straight over-the-top guy. You get a get a better look at the ball."
Brown went 1 for 4 Monday.
Including last season, it was Brown's third start against a lefty. He went 1 for 13 against lefties a year ago.
"I hit lefties pretty well in the minor leagues," Brown said. "You have to keep your right shoulder in, or you can't get to the ball. You have to stay balanced. Charlie's working me in there slow to make sure I'm ready."
Brown batted .331 with a .376 on-base percentage against lefties in the minors last season.
Test for Utley
For the first time since he came off the DL on May 23, Chase Utley started for the fourth straight day Monday. Manuel said he sees no effects from Utley's right knee condition.
"He's running good. He feels good," Manuel said. "Three days in a row was a step for him, and now today's the fourth, so we'll see where's he's at."
Placido Polanco leads all third basemen in fans' balloting for the NL all-star team with 1,303,817 votes. Rollins is second among shortstops and Utley is third among second basemen. . . .
