BALTIMORE -- Corey Patterson homered and had three RBIs, and the Baltimore Orioles withstood four home runs by the Tampa Bay Rays in an 8-7 victory Sunday.

Baltimore took two of three from the Rays, who remained 2 1/2 games behind the first-place New York Yankees in the AL East. It was only the second time in 14 tries that the Orioles won the finale to take a three-game series.

Tampa Bay scored all its runs on homers by Ben Zobrist, Evan Longoria, B.J. Upton and Rocco Baldelli.

After the Rays used two-run drives by Longoria and Upton to take a 5-4 lead in the sixth inning, Baltimore scored four runs in the bottom half against three Tampa Bay relievers.

Dan Wheeler (2-2) issued successive one-out walks before former Wolf Pack pitcher Chad Qualls gave up RBI singles to Josh Bell, Brian Roberts and Nick Markakis. Luke Scott added a sacrifice fly off Randy Choate.

Baldelli hit a two-run, pinch-hit homer off Mike Gonzalez in the seventh to make it 8-7.

Alfredo Simon (4-2) worked a perfect eighth and Koji Uehara got three straight outs for his sixth save.

Orioles starter Chris Tillman allowed three runs and six hits in 5 1/3 innings. Recalled from Triple-A Norfolk before the game, Tillman retired the side in order only once and was aided by two double plays.

Riding a six-game win streak, Rays starter Wade Davis gave up four runs and six hits in five innings.

After Tampa Bay wasted a two-out triple by Carl Crawford in the top of the first, Baltimore took a 2-0 lead in the bottom half. Brian Roberts walked and was caught leaning toward second when Davis threw wildly on a pickoff attempt. Roberts ended up on third and scored on a single by Markakis, who advanced on two walks and came home on a sacrifice fly by Patterson.

Zobrist ended a 1-for-15 slide in the third with his eighth home run. In the Baltimore half, Felix Pie walked and Patterson hit a high fly to right that cleared the 25-foot scoreboard for a 4-1 lead.

In the Tampa Bay fourth, Matt Joyce hit a triple and Upton drew a two-out walk before Roberts made a sensational diving catch of a liner to second base that appeared destined to make it to the outfield.
