Boston ? Curt Schilling came to Boston four years ago with the lone goal of helping the Red Sox win the World Series.

He might do it twice.

In what could be his final start in a Boston uniform, Schilling held the Rockies to one run over 51â3 innings in Game 2 of the Series on Thursday night to lead the Red Sox to a 2-1 victory over Colorado and open a 2-0 lead in the best-of-seven series.

Schilling struck out four while allowing four hits and two walks and gave Boston a chance to sweep the Series at Coors Field. Unless the Rockies can win twice at home to force a sixth game, Schilling has pitched his last game before he becomes eligible for free agency.

“I guarantee you, everybody’s as sick of hearing about it as I am,” said Schilling, who waved his cap to all corners of the ballpark as he left to a deafening ovation. “Whatever happens is going to happen. They know what I want. They know I want to come back. We’ll deal with it after the World Series.”

If he leaves, Schilling will have accomplished his professed goal and so much more: In four years, he has become a hero at Fenway and across the blogosphere, and a potential Hall of Famer.

The success is the result of a “will to make sure the score ends up in our favor,” said Terry Francona, who also managed Schilling with the Philadelphia Phillies. “I’ve been around him so long, I probably expect unfair things out of him. But that probably won’t stop.”

Hideki Okajima and Jonathan Papelbon finished up for the Red Sox, allowing one hit over the final 32â3 to protect the one-run led.

“That was just phenomenal to watch. A 2-1 game in the fifth that ends up 2-1,” Schilling said. “Much like all year, our bullpen’s been dominating.”

With this start, Schilling’s career postseason record improved to 11-2. Included among those wins were his famous bloody sock victories over the New York Yankees and the St. Louis Cardinals in 2004, on the way to Boston’s first World Series title in 86 years.

Schilling’s victory gives the Red Sox a chance to repeat the feat.

Fresh off the disappointment of Boston’s disaster at Yankee Stadium in the 2003 ALCS, general manager Theo Epstein and his staff flew to Schilling’s house in Arizona to persuade him to waive his no-trade clause and accept a lucrative contract extension with the Red Sox.

“He’s a competitor. He got the better of us,” Rockies manager Clint Hurdle said.
