Their starting pitcher didn't give them much of a chance Monday afternoon, and the bottom of the order couldn't deliver when badly needed in a tight spot as evening arrived.

A bullpen that has been terrific so far this postseason had to be run almost completely out of gas.

The Texas Rangers, though, still had Nelson Cruz, who a week ago wouldn't have inspired much confidence at the plate. But the right fielder, who hit six homers in last year's run to the World Series, put his team within two victories of another Fall Classic.

Cruz tied Game 2 of the American League Championship Series with a solo homer in the seventh, and won it with the first walk-off grand slam in postseason history as the Rangers beat Detroit 7-3.

Five relievers, led by right-hander Scott Feldman, tossed 8 1/3 scoreless innings to give the Rangers and Cruz a chance to rally from a 3-2 hole created when starter Derek Holland couldn't command his pitches.

Cruz, though, ended it with his ninth career postseason homer to give the Rangers a 2-0 lead in the best-of-seven series.

"You cannot describe the way I feel right now," said Cruz, who took a shaving-cream pie to the face and a beer shower after the fifth game-ending homer of his career.

"It was amazing. It's special. When you get a chance to get a W, that's the most important thing. I'm just happy to get the W for the fans and my teammates."

Cruz almost didn't get the chance to win the game. He tied it at 3-3 in the seventh with a leadoff homer against Max Scherzer that clanged off the left-field foul pole.

In the ninth, after Adrian Beltre doubled and Mike Napoli was walked intentionally, Cruz was plunked just above the right wrist by a Jose Valverde fastball.
