After the Dodgers evened the National League Division Series by beating the St. Louis Cardinals in Game 2 on Saturday night, Clayton Kershaw was a possibility to start Game 4 Tuesday on short rest.

Adam Wainwright did not.

Dodgers manager Don Mattingly said that Kershaw “wants to throw” when the Cardinals land in St. Louis tomorrow.

“So when we get there a few guys that want to throw and things like that, we’ll talk about Game 4 probably on the plane,” Mattingly said. “We’ll see where we’re at with that.”

Dan Haren threw a bullpen session Saturday at Dodger Stadium, lining him up to start the game. He went 13-11 with a 4.02 earned-run average in the regular season. The veteran right-hander has only started two playoff games in his career and none since 2006, when he tossed five innings in a losing effort for the Oakland A’s in the American League Championship Series.

In Game 1 on Friday, Kershaw allowed eight runs for just the second time in his career. He went 21-3 with a 1.77 ERA in the regular season.

Wainwright, the Cardinals’ ace, struggled in Game 1 too. Cardinals manager Mike Matheny said before the game that he’s leaning toward starting someone else — likely right-hander Shelby Miller — in Game 4.

“I never want to hem ourselves in here and say that we won’t do something,” Matheny said, “but I think with what we saw (Friday) and how hard (Wainwright) has had to push so far down the stretch here, I think it would be a pretty good stretch to see him go on short rest. But stranger things have happened.”
