Josh Hamilton hit a three-run homer to increase his major league-leading RBI total to 103, and the Texas Rangers beat All-Star pitcher Justin Duchscherer and the Oakland Athletics 9-4 on Saturday.

The night before, Hamilton hit a two-run shot and reached 100 RBIs for the first time in his career _ in his 99th game of the season, no less.

Chris Davis hit a solo homer and doubled in a run, Marlon Byrd added a solo shot and Jarrod Saltalamacchia had a two-run double for Texas, which took the lead in the third. But Duchscherer settled down and retired eight straight during one stretch before running into more trouble.

Davis' homer to start the seventh was the first of four straight hits off Duchscherer, and Michael Young's RBI single chased the right-hander. Duchscherer (10-7) is winless in three starts since the All-Star break and lost for only the second time in 10 starts at home. He allowed season highs of nine hits and eight earned runs after not having yielded more than three earned runs all year.

Emil Brown and Mark Ellis each hit a solo homer, Bobby Crosby had an RBI single and Wes Bankston added a sacrifice fly for the A's, who lost their third straight and ninth in 10 games.

Texas designated hitter Milton Bradley was ejected in the third for arguing a called third strike that ended the Rangers' half.

Matt Harrison (2-1) went five innings for the win and Josh Rupe pitched three scoreless innings of relief. Warner Madrigal allowed Ellis' homer to start the ninth.

Harrison found himself in a jam right away, allowing consecutive one-out walks to Carlos Gonzalez and Kurt Suzuki in the first before pitching coach Mark Connor paid him a mound visit during Brown's at-bat. Harrison got Brown to fly out and then escaped unscathed when Crosby popped up to first.

The Rangers are 8-3 against the A's this year and moved into second place in the AL West with Friday night's 14-6 victory.

The A's scored a pair of unearned runs in the third to pull to 3-2. After one-out singles by Gonzalez and Suzuki, Brown reached on Young's fielding error at shortstop. Crosby followed with his run-scoring single and then Bankston hit a sacrifice fly.
