Gregerson shares emotions of playing in Classic

PEORIA, Ariz. -- Padres reliever Luke Gregerson returned to big league camp on Sunday and shared his experience playing for Team USA in the World Baseball Classic.

"The experience was unbelievable," Gregerson said.

As strange as it might sound, Gregerson's father, Duke, might have actually had more fun than his son.

"My dad was like a kid," Gregerson said. "He came to all of the games. And then going out there and to have success and see him after … he was almost starry-eyed."

Gregerson appeared in two games, tossing two shutout innings. He struck out two and didn't allow a hit or a walk for a team that was eliminated by Puerto Rico in the second round in Miami.

"Getting to wear that 'USA' across your chest, that was something that I'll never forget," Gregerson said. "Playing with some of the best players in the world and to have your name associated alongside them is pretty neat. I hope I get to do it again."

On Saturday, Padres teammate Chris Denorfia commented on the level of "very high-intensity baseball." Gregerson felt the same way, likening the atmosphere to the final three games of the 2010 season when the Padres faced the Giants at AT&T Park with a playoff spot hanging in the balance.

"Your adrenaline was through the roof," Gregerson said. "I was more nervous and amped up sitting in the bullpen watching the game than when I was out there throwing. I was so nervous for everyone. My chest was hurting. I wanted everyone to do so well."
