KANSAS CITY, Mo.

Madison Bumgarner was limbering up at Kauffman Stadium this week, getting loose with his San Francisco teammates near the dugout, when Tim Hudson and Michael Morse sneaked up from behind and playfully ruffled the pitcher’s long, scraggly locks.

That was way too hairy for Bumgarner. He quickly spun and playfully sparred with his pals.

They were about only ones who could touch Bumgarner in this World Series.

“Yeah, it was hopeless,” Kansas City manager Ned Yost said.

The 25-year-old Bumgarner capped off a performance for the ages and earned Most Valuable Player honors Wednesday night, pitching five scoreless innings of relief in Game 7, as the Giants held off the Kansas City Royals 3-2.

Moments after he retired Salvador Perez on a foul pop with a runner on third base for the final out, Bumgarner insisted he wasn’t worn down. About a half-hour later, he felt a bit differently.

“You know what? I can’t lie to you anymore,” he said. “I’m a little tired now.”

Bumgarner earned a sensational save to go along with two sparkling wins as a starter in the Series. That on top of being MVP of the National League Championship Series and pitching a record 52 2/3 innings in this postseason.

Put it this way: Bumgarner threw two shutouts in October, starting with a win at Pittsburgh in the wild-card game. Washington’s Jordan Zimmermann was the only other pitcher to reach the ninth inning this postseason, and he got pulled.

All tremendous accomplishments, but it was hard to tell from listening or watching to the 6-5 Bumgarner. He shows virtually no emotion on the mound, and he seems to be the only person unimpressed by what he’s done.

Funny thing, the slow-moving lefty was carrying an energy bar with him when he kidded around with Hudson and Morse before Game 6.

“He’s such a humble guy, and we rode him pretty good,” Giants’ manager Bruce Bochy said.

“It’s historic what this kid has done,” he said. “Really, truly amazing.”

After winning the opener with seven impressive innings, Bumgarner threw a shutout in Game 5. And when the Royals forced a Game 7, there was little doubt that the guy called MadBum would be called on to pitch again on two days’ rest.

But five innings of relief? Who would’ve believed that?

“I wasn’t thinking about innings or pitch count. I was just thinking about getting outs, getting outs until I couldn’t get them anymore and we needed someone else,” Bumgarner said. “Fortunately, was able to get some quick innings, and I was able to stay in there.”

Bumgarner boosted his World Series stats to numbers never seen before: 4-0 with a 0.25 earned-run average, along with three championship rings. In 36 innings, he’s allowed just one run and 14 hits, striking out 31 and walking five.

Bumgarner wound up slinging 68 pitches and finished with 270 innings this season. He went 5-1 with a 1.03 ERA this postseason.

Last weekend, former St. Louis Cardinals catcher Tim McCarver paid tribute to the Giants’ ace.

“It’s Gibson-esque, if you will. I know Bob could do that, and I saw that from a 60-feet, 6-inch view of him every outing he threw in the World Series. I see the same thing in Bumgarner. I really admire that,” McCarver said.

Before Game 7, Jack Morris praised Bumgarner. Morris knows well about Game 7 – always intense, he threw a 10-inning shutout in 1991 to lift Minnesota over Atlanta.

“I want to hug him,” Morris said near the backstop, a couple of hours before gametime. “He’s my kind of guy.”

“He’s got the same emotions; he just doesn’t show them. He’s got a big furnace burning right now,” he said.

A lot of stamina, too.

But in this era where pitch counts are so precious, Bumgarner wasn’t worried about his arm in Game 7. And if he was OK, so was Bochy.

“In fact, I was staying away from him every inning, because I was hoping he wouldn’t go, ‘I’m starting to get a little tired,’ because there’s no way I would have taken him out unless he would have told me that,” Bochy said.

All-Star catcher Buster Posey said there wasn’t much conversation on the bench with Bochy, Bumgarner or pitching coach Dave Righetti, either.

“Not much of anything. I think everybody could see how good he was,” Posey said. “They weren’t putting great swings on him.”

No, they weren’t.

“We probably would have won if they didn’t have him,” Royals star Lorenzo Cain said. “But they do have him.”
