CLEVELAND -- Lou Montanez has earned the right to swing away after one week in the majors.
The Orioles sent 13 men to bat in the eighth, getting six hits and three walks in their largest inning of the season. Baltimore has scored 55 runs in its last seven games.
Montanez came up in the eighth with runners on first and second, none out, and expected manager Dave Trembley to ask him to bunt.
"I thought about that, but they let me swing," Montanez said. "I got a good pitch to hit."
Trembley insisted a bunt didn't enter his mind.
"Why bunt the eighth guy in the order?" Trembley said. "To get the No. 9 hitter up there? Montanez has been swinging at strikes, getting big hits."
Montanez, who became the first Oriole in 45 years to homer in his first time up in the majors on Aug. 6, is hitting .474 (9-for-19) overall.
Kevin Millar singled to center off Rafael Perez (2-3) to start the rally.
"He's tough," Millar said of the lanky left-hander. "He's got really good stuff. When you get an inning going against him, it's pretty big."
Third baseman Andy Gonzalez then mishandled a sharp grounder off the bat of Jay Payton for an error, and Montanez doubled off the wall in right-center, scoring Millar to break a 3-3 tie.
Juan Castro lined a two-run single and Melvin Mora an RBI double to make it 7-3. Edward Mujica walked Ramon Hernandez with the bases loaded, Millar lined a two-run single and Montanez finished the scoring with an RBI single.
"You usually don't see two guys get two hits in the same inning," Millar said. "We've got a good, balanced lineup."
Fernando Cabrera (1-1) worked a perfect seventh for his first win since April 25, 2007, when he was with Cleveland. He signed with Baltimore last August after being released by the Indians.
Zach Jackson, one of four players acquired by Cleveland in the July 7 trade of CC Sabathia to Milwaukee, didn't get much defensive help in his Indians debut. A missed grounder and a ball lost in the twilight contributed to two of the three runs the left-hander allowed over five innings.
"We didn't play well at all in multiple areas," Indians manager Eric Wedge said. "It got away from us. Perez didn't have it and Mujica struggled as well."
Jackson gave up four hits and two runs in the first. With runners on second and third, Aubrey Huff got an RBI on a grounder that second baseman Asdrubal Cabrera couldn't handle near the bag for an error. Hernandez's single to left made it 2-0.
Shin-Soo Choo's two-run double with two outs in the bottom half off Daniel Cabrera tied it.
Daniel Cabrera, who leads the AL in walks (73), wild pitches (14) and hit batters (17) plunked Grady Sizemore in the right knee in the second and drilled Jhonny Peralta in the left hand in the third. Peralta played until being lifted for a pinch hitter in the seventh and was taken to a hospital for examination.
"The X-rays were negative and he's day-to-day," Wedge said.
Baltimore went ahead 3-2 on consecutive ground-rule doubles with two outs in the fifth.
Aubrey Huff's liner one-hopped over the wall in right-center. Then Hernandez hit a fly ball that both Sizemore in center and Choo in right lost in the changing sky. The ball plopped onto the warning track and over the wall in nearly the same spot.
Asdrubal Cabrera's two-out double to right-center tied it in the sixth.
Franklin Gutierrez hit a solo homer in Cleveland's three-run ninth off Alberto Castillo.
