Tiger Woods and his wife Elin are expecting their first child this summer. Woods celebrated his 31st birthday yesterday.

"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."

Tiger is skipping the season-opening Mercedes-Benz Championship next week in Maui. "I'm going to stick close to home for the next few weeks," he said. Woods will start his '07 season 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."
