OAKLAND, Calif. — Waking up early to accommodate requests following his perfect game Saturday has prepared White Sox pitcher Philip Humber for one important task.

Humber's wife Kristan is expecting the couple's first child on May 8.

Humber admitted he was tired after handling the media requests but appreciated hearing experiences in a telephone conversation Monday with the Sox's No. 1 fan — President Barack Obama.

"It definitely is an honor to speak to him," said Humber, who was named the American League player of the week for April 16-22. "He just wanted to congratulate me. He even asked about Kristan and the baby and asked about how that was going.

"He shared some of his experience of being a new father. He's a very nice man, and he represents our country in a good way. He's definitely a great communicator, and I appreciate him talking to me."

Monday's activities consisted of several radio interviews, the Sox's lowering ticket prices for Thursday night's game — Humber's next start, against the Red Sox — and reciting the popular Top 10 list on "The Late Show With David Letterman."

"I think it went (well)," Humber said. "I can't wait to see it, and hopefully I didn't embarrass myself too bad. It sounded like I got some laughs."

Despite the price of fame, Humber is content to make the most of it.

"I'm just trying to be myself, and I know it's something that's like your 15 minutes of fame or whatever," he said. "I really try as much as I can to represent what I believe in and represent the White Sox well. I just want to be appreciative of it. It's throwing a perfect game.

"Like I was telling people, it's not something you do, but it's something that happens to you. Enjoy the moment and try to remember all of it. But at the same time, our guys have done a good job of getting most of it out of the way."

Extra innings: Humber and the Athletics' Dallas Braden are the only pitchers who have thrown a perfect game to go to a three-ball count on the 27th batter, according to the Society for American Baseball Research. According to SABR, Humber also threw the fewest balls (29) since David Cone in 1999. ... Despite his productive hitting, A.J. Pierzynski might sit Tuesday night. Manager Robin Ventura indicated he might start Tyler Flowers at catcher against left-hander Tommy Milone.
