HOUSTON (AP) — Lance Berkman hit a two-run single after an umpire’s missed call in the sixth inning, and the Houston Astros went on to beat the Texas Rangers 6-1 Saturday night.

The Astros won for the seventh time in 10 home games. Texas has lost nine of 12.

The game was tied at 1 when Hunter Pence and Morgan Ensberg led off the Houston sixth with singles against John Koronka (0-1), called up from the minors earlier in the day to make his first start of the season.

Carlos Lee beat out a bunt to load the bases and Texas manager Ron Washington brought in reliever Scott Feldman, who balked home a run the previous night.

Brad Ausmus grounded into a double play, with Pence scoring the go-ahead run. Pinch-hitter Mike Lamb walked and Craig Biggio hit an RBI single for a 3-1 lead.

Shortstop Michael Young then fielded Mark Loretta’s grounder and flipped to third baseman Travis Metcalf, who touched the bag to clearly force out Lamb. Third-base umpire Tim Timmons called Lamb safe, however, and Washington argued.

C.J. Wilson relieved and Berkman hit a sinking liner that Sammy Sosa couldn't reach in shallow right field. Lee drove in Loretta with Houston’s fourth straight single.

Wandy Rodriguez (2-3) allowed four hits and struck out seven in six innings.

Brad Lidge retired six of the seven batters he faced in relief and Chad Qualls pitched a scoreless ninth for Houston.
