Jake Peavy and the San Francisco Giants hoped Game 6 of the World Series would result in a parade.

It did, all right — a parade of Kansas City runs.

In the worst outing of his fine career, Peavy watched the Royals march around the bases on their way to an early blowout, routing the Giants 10-0 Tuesday night to force a Game 7.

Always intense and vocal on the mound, Peavy walked to the dugout without any expression when he got pulled in the middle of a seven-run second inning that turned on a grounder botched by first baseman Brandon Belt.

On this night, there wasn't much for the Giants to say.

One good thing did happen for manager Bruce Bochy: It was so one-sided early, he was able to preserve his best relievers for Wednesday night. That bullpen includes ace starter Madison Bumgarner, who has already volunteered to pitch if needed.

A day earlier, Peavy sat at the podium with two of his young sons for a playful news conference. The pitcher was asked whether his family had thought about buying a San Francisco cable car — a real one, as a souvenir — if the Giants won.

Peavy was coy, saying that decision was for another day. But fifth-grader Wyatt whispered in his dad's ear: "We picked out a trolley car."

The Royals quickly put the brakes on that purchase.

Now, San Francisco will have to reverse a most daunting trend. Home teams have won the last nine Game 7s in the World Series. The Giants are 0-4 when a best-of-seven Series has been pushed to the limit, most recently when Barry Bonds & Co. lost to the Angels on the road in 2002.

Peavy retired the first two batters of the game, then things unraveled in a hurry. The right-hander wound up escaping a two-on jam in the opening inning, showing no ill effects from a foul ball that rattled into the Giants' dugout in Game 3 and cut the thumb on his pitching hand.

In the second, it all fell apart.

Mike Moustakas was able to ground an RBI double between a diving Belt and the bag for a 1-0 lead. Alcides Escobar came up with runners on second and third and no outs, and hit a grounder to the right side.

Belt ranged far off the base, looked to see if he had a play at home — the runner held — and then missed his tag on a diving Escobar. Peavy appeared to be yelling all along for Belt to throw home, and the misplay seemed to open the door for the Royals.

Nori Aoki followed with an RBI single, and that was all for Peavy.

The 33-year-old Peavy was charged with five runs and six hits with a walk in just 1 1-3 innings.

It was the second-shortest of 346 career starts for Peavy over 13 seasons — in 2009, two years after winning the NL Cy Young Award with San Diego, he gave up four runs in one inning.

Peavy sat quietly in the dugout as the Royals kept scoring in the big second inning. By the time it ended, he was left with 7.98 ERA in nine postseason starts — and a 9.58 mark in three World Series tries.
