PITTSBURGH (AP) — Charlie Morton came off the disabled list to gain his first victory since July 2, and the Pittsburgh Pirates defeated the Boston Red Sox 4-0 Tuesday night for their ninth win in 11 games. Sidelined since Aug. 16 because of right hip inflammation and a sports hernia, Morton (6-12) allowed four hits in five innings, struck out six and walked two. Five relievers combined on three-hit relief, completing the Pirates' eighth shutout this season. Russell Martin hit a two-run homer in the second inning off rookie Anthony Ranaudo (3-3), and Starling Marte added a solo shot in the sixth.
