"They really showed me some character tonight," Baltimore manager Sam Perlozzo said. "I know when they came into the dugout and it was 7-3, they were still chirping about coming back. Miguel Tejada was saying, 'Let's go, we can get them.' "
"You can get waxed like we did last night and come back and put a performance together like we did tonight," Conine said. "It's a good thing, and it does a lot for your confidence."
Jhonny Peralta, Victor Martinez and Aaron Boone homered for Cleveland, which had beaten Baltimore five straight times. Martinez extended his hitting streak to 14 games, the longest in the major leagues this year.
A night after a 15-1 loss to the Indians, the Orioles had a season-high 21 hits and batted around in the fifth and eighth innings. It was Baltimore's highest-scoring game since a club-record 23 runs against Toronto on Sept. 28. 2000, at Camden Yards.
Conine had three hits, matching his season total in one game. Every Oriole starter had at least one RBI except for Brian Roberts -- who reached base four times and scored twice.
"We came back and got a couple of rallies going in a few innings," Patterson said. "We played well. What can I say? We all contributed."
Jake Westbrook (2-2) failed to protect a 7-3 lead, allowing nine runs -- eight earned -- and 12 hits in 4 2/3 innings.
"I just think he was over the middle of the plate and they were swinging the bats well tonight," said Indians manager Eric Wedge, who closed his clubhouse to reporters. "It was a bad night, all the way around. It's one game."
Tejada's one-out RBI single in the fifth and Ramon Hernandez's two-out, run-scoring single cut the lead to 7-5, Javy Lopez hit an RBI double and Millar followed with a two-run double that bounced over the center-field fence.
Matt Miller relieved, and Patterson, who entered the game hitting .067, hit his second pitch into the right-center seats for his first AL homer and a 10-7 lead.
"This is one of the nights that we picked up our pitcher," Gibbons said. "There is going to be other nights where we're going to win 2-1 (and) they're going to have to pick us up. It was a good night to explode after what happened last night."
Grady Sizemore hit an RBI sacrifice fly in the eighth. Hernandez's three-run homer highlighted a five-run eighth.
Baltimore starter Rodrigo Lopez gave up seven runs and nine hits in 4 1/3 innings. He has allowed seven homers this year, including five in his last two outings.
- The Orioles stole two bases against Martinez, who has failed to nab any of the 13 attempted thefts against him this year.
- A catcher's interference call against Martinez led to the first unearned run of the year by an Indians starter.
- Miller (right elbow strain) and Betancourt (upper back strain) left in the sixth. Wedge said one of the pitchers would probably have to go on the disabled list.
- Cleveland's Kelly Shoppach had his first major league hit, a pinch single in the ninth.
