Madison Bumgarner says he'll be available out of the bullpen as the San Francisco Giants look to close out the World Series in Kansas City on Tuesday night.

Bumgarner pitched a four-hit shutout in Game 5 on Sunday night.

The right-hander hasn't made a relief appearance since the 2010 playoffs.

Bumgarner, who threw 117 pitches Sunday, wouldn't estimate how long he could go.

"I'm not a big pitch-count guy," he said. "So as long as you keep getting outs and you feel good, you should stay out there."
