Ian Kinsler got Texas started with a leadoff homer, Matt Harrison earned his 18th victory and the AL West-leading Rangers held on to win 9-7 Thursday for a four-game split with the chasing Oakland Athletics.
The two-time defending American League champion Rangers (92-64) have a four-game division lead over the A's with six to play, including three games in Oakland next week.
Kinsler's 19th homer, his majors-best seventh leadoff shot this season, started a five-run first for the Rangers against Travis Blackley (5-4). The Rangers had four consecutive two-out hits, capped by Mike Napoli's two-run homer.
Harrison (18-10) went six innings, allowing four runs and seven hits, to become the Rangers' first 18-game winner since Kenny Rogers in 2004.
