Framber Valdez threw an 83-pitch complete game in his last start and returns to the mound for the Houston Astros as they end a three-game series in Pittsburgh. Mitch Keller (1-7, 3.73) pitches for Pittsburgh.

Pittsburgh's Mike Burrows held Houston in check into the sixth inning to pick up the first victory of his career as a starter as the Pirates topped the Astros 3-0.

The Pirates dropped 2 of 3 games at the San Diego Padres, losing 6-4 as +133 underdogs in the Sunday finale with the Over (8.5) hitting. Pittsburgh held an 83.9% win probability, according to ESPN Analytics, leading 4-1 with 1 out in the bottom of the sixth inning Sunday -- but was outscored 5-0 the rest of the way.
