ARLINGTON, Texas (AP) - The Rangers moved within a half-game of AL West leading Houston, when Prince Fielder hit a tiebreaking, two-run homer in the eighth inning to lead Texas to a 5-3 win over the Astros on Monday night in the opener of a pivotal four-game series.
Mitch Moreland hit his team-leading 20th home run for Texas, which has won four straight against the Astros and leads the season series 9-4.
Fielder's homer came on 3-2 pitch from Will Harris (5-4). He had two hits and scored three times.
Keone Kela (7-5) got the win, retiring one of two batters, and Shawn Tolleson earned his 32nd save in 34 attempts.
The Astros' Jose Altuve hit Cole Hamels' sixth pitch of the game for his 12th homer of the year.
