Only at Bodog Sportsbook can you bet on what you think the sex of Tiger Woods’ first baby will be!

The world’s no. 1 golfer turned 31 on Saturday and surprised friends and family by sharing some pretty big news: his wife, Elin Nordegren, is expecting their first child this summer.

“Obviously, we couldn’t be happier and our families are thrilled,” Woods said on his Web site. “I have always wanted to be a dad. I just wish my father could be around to share the experience.”

Woods and Nordegren of Sweden married in October 2004, and although he did not say when in the summer the baby is due, simple math tells us it will likely happen sometime between the US Open and British Open.

So, that means the world’s No. 1 player will skip the season-opening Mercedes-Benz Championship next week on Maui.

“I’m going to stick close to home for the next few weeks,” he said. Woods will start his 2007 season playing in the Buick Invitational at the end of January, “which will allow Elin and I to spend more time with our families during this very special time in our lives.”

It seems like Tiger’s days as a globe-trotting trophy hunter are numbered.
