NEW YORK -- The Detroit Tigers got a big boost from Anibal Sanchez's arm and a helping hand from an umpire, too.

The reward: a commanding two-games-to-none lead in the A.L. Championship Series and a trip home with their ace ready to start.

Sanchez shut down a Yankees lineup minus injured Derek Jeter, and Detroit scored twice after an admitted missed call by an umpire to beat New York 3-0 Sunday.

"He was terrific," Detroit manager Jim Leyland said of Sanchez. "This is a tough place to pitch with a tough lineup and a short porch. And a whole bunch of left-handed hitters, it is not easy. That was quite a feat."

Yankees starter Hiroki Kuroda was perfect through five innings to keep pace with Sanchez. But the slumping Yankees hitters were no match for the 28-year-old right-hander a day after their captain broke his ankle in the 12th inning of a 6-4 loss.

Making his second postseason start, Sanchez threw three-hit ball deep into the game to make Leyland's job easier. Closer Jose Valverde gave up four runs in the ninth Saturday and, only hours later, Leyland said the right-hander wouldn't close Game 2.

Delmon Young gave Sanchez his first run of support with a fielder's-choice grounder in the seventh. The Tigers then scored twice in the eighth after umpire Jeff Nelson missed a call on a two-out tag at second base.

The Tigers led 1-0 in the eighth and had Omar Infante on first with two outs. Austin Jackson singled, and when Infante took a wide turn at second, right fielder Nick Swisher threw behind him.

Cano made a swipe tag as Infante dove headfirst back to second. Cano missed Infante's arm but brushed his body. Still, Nelson called Infante safe.

"I think the umpire got confused 'cause he saw my hand, something with my hand made him think I was safe," Infante said.

Was he out?

"Of course," Infante said.

Yankees manager Joe Girardi argued and was ejected on his 48th birthday. After the game, Nelson saw a replay and acknowledged his mistake.

"The hand did not get in before the tag," he said. "The call was incorrect."

Game 3 in the best-of-seven series is Tuesday in Detroit, with reigning A.L. MVP Justin Verlander starting for the Tigers against Phil Hughes.
