BALTIMORE -- Baltimore's Chris Davis crushed his major league-leading 46th home run, and Wei-Yin Chen allowed just two runs over seven innings, leading the Orioles to a 4-2 victory over the Tampa Bay Rays on Wednesday.
Baltimore avoided a three-game sweep and knocked Tampa Bay out of first place in the American League East and behind the Boston Red Sox.
Davis tied Jim Gentile (1961) for third on the Orioles' single-season home run list, behind Brady Anderson (50 in 1996) and Frank Robinson (49 in 1966).
Chen (7-6) snapped a three-game losing streak and allowed seven hits with three strikeouts and three walks. His last win came July 30 against the Houston. Tommy Hunter picked up his fourth save for Baltimore.
Adam Jones went 2-for-4 and hit his 26th home run of the season. Nate McLouth also went 2-for-3 with a run for the Orioles, who won for just the fourth time in their past 11 games.
Rays starter Jeremy Hellickson (10-7) struggled with his command most of the night, allowing four runs on seven hits with three strikeouts and three walks over 4 1/3 innings. He also failed to get past the fifth inning in four of his past five starts.
Jason Bourgeois hit his first home run for the Rays since being called up Aug. 6. Sean Rodriguez also got his third home run for Tampa Bay.
Baltimore opened a 2-0 lead in the first on a fielder's choice by Adam Jones and sacrifice fly by Matt Wieters. The Rays cut the margin to 2-1 in the second on a two-out, solo home run by Bourgeois that was roped to left field.
Jones then provided another two-run cushion when he led off the third with a long solo home run to center. It was his fourth career homer off Hellickson in 40 at-bats.
On a warm night at Oriole Park, the ball continued to travel and a solo homer by Rodriguez cut the Orioles' lead to 3-2 in the fourth.
The Orioles were just 0-for-6 with runners in scoring position against Hellickson, but were effective with the long ball. Davis hit the 74th home run to land on Eutaw Street, increasing the lead to 4-1 in the fifth.
