Kemp, who suffered a slight shoulder separation when he slammed into the right-field wall at Dodger Stadium on April 9, was on a flight back to Los Angeles on Friday to be examined by trainer Stan Conte after he felt a twinge in his shoulder while making a throw in the first inning of Wednesday's game.
"Right now, it's just a precautionary thing," Conte said. "He said he felt a twinge in his shoulder so I want to get him back here and take a look at it."
Kemp played five innings for the 51s and went 0-for-3, but it was a throw he made from the outfield in the first inning that bothered him. Manager Grady Little said Kemp continued to play and didn't feel any discomfort until the following morning.
"His shoulder was still a little sore, so we're going to wait a few days before we push him again," Little said. "Were going to slow him down a little bit on his movement forward."
Kemp has played in five games for the Dodgers this season and was batting .438 with seven RBIs and a double before he was injured. Brady Clark, who was acquired from the Milwaukee Brewers on March 27, has done a good job as the only right-handed-hitting outfielder for the Dodgers. In 15 games, Clark is hitting .368 with three doubles and two RBIs.
The major concern for the Dodgers is not to re-injure Kemp's shoulder because he is eligible to be activated from the disabled list on Wednesday.
"He doesn't feel confident in his shoulder right now," Conte said. "Sometimes when a player is injured, he needs to get his confidence back, and Kemp is a little unsure of his shoulder right now."
The Dodgers hope that Kemp can resume his rehabilitation with the 51s as early as next week.
Brazoban to pitch: Yhency Brazoban, who is recovering from Tommy John elbow reconstruction surgery, started Friday night for the Class A Inland Empire 66ers in his second rehabilitation assignment. Brazoban was expected to come out of the bullpen, but because of rain in the area, the Dodgers decided to start him to avoid having him pitch on a sloppy mound.
Little said the Dodgers have instructed officials in Lancaster to take Brazoban out of the game if field conditions become too sloppy. Brazoban is expected to throw two innings or 40 pitches, and both Little and Conte said the reliever would not throw more than that.
Field conditions a concern: With the outfield at Dodger Stadium wet because of rain throughout the day Friday, the main concern for the Dodgers was player safety.
"The No. 1 concern you have when you have conditions like this is that no one gets hurt," Little said as rain continued to fall prior to the game. "You don't want to put anyone in a position where they have a good chance to get hurt."
Right fielder Andre Either said he wasn't concerned about injury, but he did say that the field conditions present some difficulties on defense.
"You have to be more cautious because the ball can skip, and it's going to be wet when you pick it up to throw," Either said. "When the field is slippery like today, you have to make sure you take good angles."
No rainout: The last rainout at Dodger Stadium was April 17, 2000.
Coming up: The Dodgers will send Brad Penny (3-0, 0.89 ERA) to the mound Saturday night at 7:10 PT against Pittsburgh's Ian Snell (1-0, 1.80).
