Charlie Morton had no expectations when he took the mound in a major league game for the first time in a month.
However, the Pittsburgh right-hander exceeded his manager's expectations as he came off the disabled list to gain his first victory since July 2, and the Pirates beat the Boston Red Sox 4-0 on Tuesday night for their ninth win in 11 games.
"I just wanted to go out and give what I got," Morton said. "I didn't know what was going to happen. I'm glad with the way it turned out."
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. He had been 0-3 with a 5.09 ERA in his eight previous starts.
"We felt we've got a guy there we needed to see where he could go and what he could bring," Pittsburgh manager Clint Hurdle said. "We didn't want to wait any longer. We wanted to see what he could bring, and adjust accordingly. He worked very hard (while on the DL) and his preparation paid off. It was a real shot in the arm."
Five pitchers combined on three-hit relief, completing the Pirates' eighth shutout this season. Boston has been blanked 15 times,
Pittsburgh entered 1½ games ahead of Milwaukee for the NL's second wild card and 3½ games behind St. Louis, the NL Central leader. The Cardinals hosted the Brewers on Tuesday night.

"There was a bad pitch in there to Martin and one to Marte," Ranaudo said. "If we look back at all my starts, the common theme is home runs, and I obviously have to do a better job."
Boston rookie Xander Bogaerts had two hits to extend his hitting streak to nine games.
