The 29-year-old Misch, who was called up from Triple-A Buffalo, gave up a run over two innings during his only appearance with the Mets this season. He appeared in 12 games in 2010, pitching to a 3.82 ERA over 37 2/3 innings.
• Right fielder Carlos Beltran will get Sunday afternoon off after playing 21 consecutive games.
Collins said Beltran didn't feel the need to get a rest, but decided it was the best move for both the 34-year-old veteran and the club.
"I don't want to fatigue those legs and have the tendinitis come back," Collins said.
Beltran came into Sunday's game batting .297 with five home runs and 18 RBIs. His on-base percentage is .383 and his OPS is .923.
• Collins said he wasn't planning to ask closer Francisco Rodriguez if he could pitch in a fourth consecutive game.
Collins indicated he'd likely go with setup man Jason Isringhausen in the ninth inning. But Collins has said that before, only to use Rodriguez instead.
Rodriguez has thrown 66 pitches over the last three days, including a 42-pitch outing on Thursday. He has a 1.17 ERA and nine saves.
• Collins didn't act apprehensive about putting catcher Ronny Paulino into the lineup, despite the fact he's never caught knuckleballer R.A. Dickey in a game before. After all, the Dodgers are sending tough southpaw Clayton Kershaw (3.38 ERA) to the hill, and Paulino owns a .341 career average against lefties.
"He'll catch R.A.'s warmup before the game," Collins said. "That will mean he's now caught him three times in the last 10 days. He's just got to relax and catch the ball."
