BOSTON – First a blowout, then a nail-biter. October ace Curt Schilling and Boston’s stingy bullpen figured out another way to stop Colorado.

Relying more on guile than pure gas, Schilling pitched the Red Sox to a 2-1 victory Thursday night and a 2-0 lead in the World Series over the suddenly stagnant Rockies.

Mike Lowell hit a tiebreaking double in the fifth and the Red Sox got 3 2/3 innings of shutout relief from Hideki Okajima and Jonathan Papelbon to win their sixth straight Series game, including a sweep of St. Louis in 2004.

That victory ended an 86-year title drought and set off a wild winter of celebrations all over New England. Two more wins this year and the party’s on again.

The Series shifts to spacious Coors Field for Game 3 on Saturday night, when $103 million rookie Daisuke Matsuzaka pitches for Boston against Josh Fogg. With no designated hitter allowed, the Red Sox must decide whether to play hobbling slugger David Ortiz at first base or leave his mighty bat on the bench.

If they keep getting this kind of pitching, it might not matter.

One night after Josh Beckett blazed through the Rockies with 97 mph fastballs in a 13-1 rout, Schilling shut them down with savvy and splitters.

Nearly automatic in October, he improved to 11-2 with a 2.23 ERA in 19 postseason starts and tipped his cap to the pulsing crowd as he walked off the mound – perhaps for the final time in a Red Sox uniform.

His fastball hovering around 87 mph, Schilling held punchless Colorado in check for 5 1/3 innings and became the second 40-year-old starter to win a World Series game. Detroit’s Kenny Rogers did it last year against the Cardinals.

Coming off eight days of rest, the wide-eyed Rockies looked awfully rusty while getting blitzed in the opener. They hardly resembled the team that had won 10 straight and 21 of 22 to earn the first pennant in their 15-year history.

Colorado came to play in Game 2. But Boston’s pitchers were too much for an offense that really hasn’t hit all month. The Rockies’ incredible charge to the pennant masked this fact: they entered Thursday batting only .235 in the postseason.

Okajima entered with two on in the sixth and Boston leading 2-1. He retired Garrett Atkins on a grounder and struck out Brad Hawpe to squash the threat.

There was more to come. The rookie left-hander from Japan fanned three straight before he was pulled for Papelbon with two outs in the eighth.

Matt Holliday spun the closer off his feet with a shot up the middle for his fourth hit. But Papelbon got even when he left the NLCS MVP sprawled in the dirt at first base with his first career pickoff.

Papelbon finished up in the ninth, securing Schilling’s third win in four starts this postseason and his second save. He and Okajima have combined for 17 1-3 scoreless innings in October.

With two outs in the fifth, Ortiz walked and Manny Ramirez singled before Lowell pulled a 2-1 pitch from Ubaldo Jimenez down the left-field line for a 2-1 Red Sox lead.

Boston loaded the bases, but Matt Herges retired Jason Varitek on an easy fly ball to end the inning.

With a bright autumn moon hanging high behind the right-field grandstand, Jimenez seemed to have the Red Sox spooked early on.

A hesitation in his windup, cap tilted slightly to the side, the 23-year-old rookie held Boston hitless for three innings with an array of 96 mph fastballs and sharp sliders. He stayed poised, too, calmly taking time to gather himself behind the mound as Boston’s big boppers stepped in.
