Munro will look to lead the Astros to their fourth straight win when they meet the Pittsburgh Pirates in the third game of a four-game set at Minute Maid Park.
Munro, signed earlier this month after he was released by the Minnesota Twins, has made four appearances for the Astros, including two starts. With Andy Pettitte still on the disabled list, Houston will look for another strong outing from Munro.
In his two starts, the 29-year-old right-hander has allowed just one earned run over 10 1-3 innings. He gave up three hits over 6 1-3 scoreless innings Friday in a 5-0 victory over the Anaheim Angels.
“We needed the win, we needed someone to come in and throw zeros,” Munro said after the game. “I was able to do it tonight. I was on a good roll tonight. There wasn’t that much stress on my legs. I still felt strong.”
Morgan Ensberg hit a two-run triple in the seventh innings Tuesday to lift the Astros to a 5-4 win.
“To me, Morgan’s an RBI guy,” Houston manager Jimy Williams said. “It was the last shot he was going to have probably and he came through big for us. That’s not unlike Morgan at all.”
It was the Astros’ second straight comeback win against the Pirates. They rallied from four runs down Monday to win 7-5.
The Pirates have lost 10 straight on the road, their longest streak since dropping 19 in a row from July 23 to Aug. 30, 1985. They have lost 15 of their last 16 in Houston.
