Rangers 4, Rockies 2: Leonys Martin doubled, tripled and drove in three runs, while Matt Harrison notched his American League-leading 10th victory as host Texas clinched its fifth straight series win.
Elvis Andrus collected three hits and an RBI and Nelson Cruz scored twice for the Rangers, who have won eight of nine.
Starting in center field for the injured Craig Gentry, Martin opened the scoring in the second inning with a two-out RBI double and scored two batters later on Andrus' two-base hit. Martin doubled the lead in the following frame, delivering a two-out, two-run triple off Colorado starter Alex White.
The three RBIs were the first of Martin's career.
Harrison (10-3), who is tied with Tampa Bay's David Price for the AL lead in wins, extended his personal winning streak to six games by tossing five scoreless innings before leaving with tightness in his lower right side. The left-hander, who allowed five hits with two walks and three strikeouts, has yielded one run in 27 1/3 frames over his last four starts.
White (2-6) departed after surrendering four runs and six hits over 2 2/3 innings.
Marco Scutaro and Carlos Gonzalez each drove in a run in the ninth for the Rockies, who went 2-13 in interleague play.
