ST. LOUIS (AP) — Peter Bourjos had no trouble calling the 310th hit in his big league career the biggest.
Hitting in the eighth spot, Bourjos singled home the winning run in the ninth inning, and the St. Louis Cardinals beat the Pittsburgh Pirates 1-0 Wednesday to stretch their winning streak to five.
"I had a walkoff hit in Anaheim, but I think at this point, we're leading the division and it's a big game in September and the one in Anaheim was in August," Bourjos said. "So this is the biggest hit."
Yadier Molina walked with two outs in the ninth on a 3-2 pitch from Mark Melancon (2-4), who had entered an inning earlier. It was the first time Melancon's pitched more than one inning since Oct. 2, 2012.
Molina advanced to second on John Jay's single and scored on the hit by Bourjos, easily beating the throw home from center fielder Andrew McCutchen.
"I was just hoping that Yadi was able to score," Bourjos said. "I wasn't too sure with McCutchen playing out there. I didn't know if he was playing shallow or deep, and I watched the play develop, and luckily Yadi was able to beat the play."
Molina saw third base coach Jose Qquendo waving an arm to send him.
"I was thinking home plate all the way," Molina said. "No one was going to stop me there."
Despite having A.J. Pierzynski on the bench, Cardinals manager Mike Matheny said he did not consider pinch-running for Molina, a slow-footed All-Star catcher.
"Two outs in that situation and we're in a tight game, his value to me being behind the plate outweighs what we're going to get on the bases from someone," Matheny said. "If he gets thrown out, it's a different conversation right now. He's done such a great job in big games, we need him out there."
St. Louis moved into sole possession of the NL Central lead for the first time Monday and extended its lead to 2 1/2 games with a three-game sweep that dropped the Pirates five games back. Pittsburgh has lost 10 of its last 12 road games, falling to a major league-worst 17-29 away from home in day games.
"They were just a little bit better than us every game," Pittsburgh manager Clint Hurdle said. "I mean, we're playing competitive baseball. We've got to find a way to score a run every now and then when we're out there and have some shutdown innings. We're not going to back down. We'll take the day off. We're going to catch our breath and try and set some stakes down in Chicago."
Trevor Rosenthal (2-6) pitched a one-hit ninth, aided by the eighth double play he's induced this season. Both of his wins have come against the Pirates on ninth-inning walkoffs.
