As difficult as things have been for Roy Halladay, what with the injuries, the ineffectiveness and the lack of confidence, he has never lost sight of the singular obsession that brought him to Philadelphia and continues to drive him even as his fastball has shifted out of the express lane.

That’s why Halladay wasn’t about to get all that giddy about winning his 200th game Sunday afternoon.

“I want to win a World Series and that’s why I’m here, that’s why I play,” the subdued and serious right-hander said after pitching eight innings of one-run ball in a 2-1 win over the Miami Marlins

“The personal milestones are great. My sons, my wife, my family -- they’re all excited about it, but for me the goal is to get to the playoffs and win a World Series. When that happens I’m going to go in the back room and yell.”

Chase Utley and Jimmy Rollins presented Halladay with a personalized magnum of champagne moments after the victory. Laynce Nix might have deserved one, too. His pinch-hit home run in the top of the ninth inning off Jon Rauch broke a 1-1 tie and put Halladay in the winner’s circle.

“It was really cool for me to be part of that,” Nix said of Halladay’s 200th.

Halladay was out of the game and already up in the clubhouse doing his postgame workout when Nix took Rauch into the second deck above right field.

“I didn’t want to screw anything up by staying in the dugout,” Halladay said. “It’s a great feeling to come out of a game and have somebody step up for you like that and be able to get a win out of it.”
