Mike Aviles kept expectations to a minimum. As a result, he maximized the opportunity.

Aviles led off the 11th inning with a homer as the Indians defeated the Orioles, 2-1, Friday night at Progressive Field. Paid attendance: 27,845.

Aviles sent lefty Brian Matusz's 1-2 breaking pitch over the left-field wall, delivering his first career walkoff homer. The Indians have belted an MLB-best seven walkoff homers.

"I was down in the count and haven't been swinging the bat well lately,'' Aviles said. "So I was just trying to figure out how to get on base, knowing Michael Brantley is hitting behind me. The ball ended up with enough backspin and got over the wall. When you don't try to do too much, good things tend to happen.''

Aviles had been 0-for-4 in the game and in a 1-for-15 slide.

Aviles owns two of the Tribe's nine walkoff hits. His RBI single defeated Minnesota on May 7.

The Indians smacked two homers to beat Baltimore at its own game. The Orioles lead the majors with 152.

"That would have been a tough one to lose,'' Indians manager Terry Francona said.

The walkoff was made possible by another superb start from Tribe ace right-hander Corey Kluber. He gave up one run on five hits in 7 2/3 innings of a no-decision. He walked two and struck out 10. He threw 76 of 116 pitches for strikes.
