Kung Fu Panda, The Freak, The Beard and all their seed-throwing buddies are on top of baseball — again.

They may be under the radar, unappreciated and unexpected. But they're unassailable, the winner of two World Series titles in the last three years.

Their sweep of the Detroit Tigers, completed Sunday night with a 4-3, 10-inning win, was simply historic.

No National League team had swept a World Series since the 1990 Cincinnati Reds.

No NL team had won twice in a three-year span since the Big Red Machine in 1975-76.

"I'm numb, really, the fact that we've won two World Series in the last three years," Giants manager Bruce Bochy said. "This will sink in, but right now, I'm kind of speechless on that."

This happens in the NL only slightly more often than appearances of Haley's Comet. They are just the fifth NL team to accomplish the feat since the 1907-08 Chicago Cubs, joining the 1921-22 New York Giants, the St. Louis Cardinals of '44 and '46, the Los Angeles Dodgers of '63 and '65, and that Big Red Machine.

And these Giants did it with small ball, becoming only the fifth big league team — and the first since the 1982 Cardinals — to win the title after finishing dead last in home runs during the regular season.

"Our guys had a date with destiny," Giants general manager Brian Sabean said.

Marco Scutaro delivered one more key hit this October, a go-ahead single with two outs in the 10th inning against Phil Coke.

On a night of biting cold, stiff breezes and some rain, the Giants sealed the title when Sergio Romo got Triple Crown winner Miguel Cabrera to look at strike three for the final out.

"Tonight was a battle," said Giants catcher Buster Posey, the NL batting champion. "And I think tonight was a fitting way for us to end it because those guys played hard. They didn't stop, and it's an unbelievable feeling."

Posey, the only player in the starting lineup when San Francisco win the 2010 clincher at Texas, celebrated with his teammates in the center of the Comerica Park diamond. In the clubhouse, they hoisted the trophy, passed it around and shouted the name of each player who held it.
