ARLINGTON, Texas--Nelson Cruz blasted the first game-winning grand slam in Major League Baseball playoff history, lifting Texas to a 7-3 win over Detroit for a 2-0 lead in their second round playoff series.

Cruz hit a towering homer into the left field stands with no outs in the bottom of the 11th inning Monday after blasting a game-tying home run four innings earlier. His walkoff grand slam came off Tigers pitcher Ryan Perry.

Cruz also homered in Texas' Game 1 3-2 victory.

Cruz got a helping hand from the Rangers' relief pitchers on Monday as the group combined to pitch 8 1/3 scoreless innings.

Game 2 was supposed to be played Sunday but organizers postponed it one day because of the threat of rain in Texas. Game 3 is Tuesday in Detroit.

Colby Lewis will start for Texas while Doug Fister gets the starting nod for the Tigers.

Meantime, Albert Pujols put on a hitting display with a home run and five RBIs as the St. Louis Cardinals crushed the Milwaukee Brewers 12-3 in Game 2 of their semi-final playoff series.

Pujols went four-for-five with three doubles for the Cardinals who rebounded from a 9-6 loss on Sunday to level the National League series at 1-1.

“When they come, they come in bunches," said Pujols. "My main job is to try and get a good pitch to hit. Once in a while when you look for your pitches you are going to hit one out of the ballpark and today they came in bunches."

Pujols smashed a two-run homer in the first inning and a two-run double in the third. He added an RBI double in the fifth and another double in the seventh.

The series now shifts to St. Louis, where Cardinals starting pitcher Chris Carpenter will face Brewers right-hander Yovani Gallardo on Wednesday.

Pujols, who can become a free agent after the World Series, was one-for-four in the game one loss.

He came into Monday's contest with only one RBI in St. Louis' first half-dozen playoff games.

“You learn from your mistakes," Pujols said.

But Brewers manager wasn't taking Pujols lightly heading into the series which will decide who goes to the World Series.

“The last time we saw them at their place he was swinging the bat just like this," Brewers manager Ron Roenicke said. "You can't make mistakes to him. You have to hit spots. You have to keep it down in the zone. He doesn't miss too many mistakes."
