HOUSTON — Pinch-runner Josh Harrison scored on a passed ball for the first of three runs in the 11th and rookie Alex Presley drove in his third run of the game later in the inning to lead the Pittsburgh Pirates to a 7-5 win over the mistake-prone Houston Astros on Sunday.

Brandon Wood doubled to start the 10th and was replaced by Harrison. Xavier Paul reached on an error when Houston closer Mark Melancon (5-3) couldn't handle his dribbler that sent Harrison to third.

He scored on a passed ball by catcher Humberto Quintero to make it 5-4. Presley followed with a single to right field that scored Paul. Presley scored on an error by reliever Aneury Rodriguez to push the lead to 7-4.
