The World Series had another bizarre ending — this time, a pickoff at first base.

One day after the Cardinals walked off (tripped off?) with a win on an obstruction call, Game 4 ended Sunday night with St. Louis pinch-runner Kolten Wong caught leaning.

Wong, his eyes red after the game, took full responsibility.

"I just got a little too far off and my back foot slipped out," Wong said. "He just made a good throw. I slipped and that's it."

It was the first postseason game in history to end on a pickoff, according to STATS. Game 3 was the first World Series game to end on an obstruction call.

On Sunday, the Cardinals were down 4-2 when pinch-hitter Allen Craig hit a ball off the right field wall with one out in the ninth. It would normally have been a double but Craig can barely run due to an ankle injury made worse when he scored on the obstruction play on Saturday.

Wong, a speedy rookie, pinch ran for Craig. After Matt Carpenter popped up, the Cardinals had just the right man at the plate as the potential tying run in Carlos Beltran, among the best postseason hitters ever.

But perhaps inexplicably, given the need for two runs, not one, Wong was caught too far off the base by closer Koji Uehara's.

Cardinals manager Mike Matheny said Wong had been told that Uehara has a good move.

"He was reminded once he got on base, and also he was reminded that the run didn't mean much, be careful, shorten up," Matheny said. "And he got a little extra, then he slipped and the slip cost him."

Wong said he had no intention of trying to steal second.

"Not at all. I was just getting ready, getting aggressive," he said. "It was a hitting situation. Carlos, he can drive the ball. If that ball got down somewhere, I was hoping to go first to third, maybe score."

Boston manager John Farrell said it wasn't a play he called.

"That was on his own," Farrell said. "It was all on Uehara."
