Jason Castro led off the 11th inning with a double and scored the go-ahead run on a close play at the plate as the Houston Astros topped the Pittsburgh Pirates 4-2 on Saturday night.

Castro doubled off the top of the center-field fence against Bryan Morris (1-2), and Carlos Pena was intentionally walked one out later. The runners moved up on a wild pitch and Castro scored when he beat second baseman Neil Walker's throw home on Matt Dominguez's fielder's choice grounder.

Pittsburgh manager Clint Hurdle argued the call with plate umpire C.B. Bucknor and was ejected. Pinch-hitter J.D. Martinez followed with an RBI single to make it 4-2.

Rookie Jose Cisnero struck out five in 3 2-3 scoreless relief innings for his first major league win. Jose Veras pitched a scoreless 11th for his sixth save.
