Tiger Woods has spent 623 weeks of his career ranked No. 1. Now, he’ll spend his 624th. More than 29 months after Woods toppled from the head of the world golf rankings, the rehabbed star roared back to No. 1 Monday after winning the Arnold Palmer Invitational. It’s Woods’s 77th PGA Tour win and his third victory so far this year, putting him back at the top for the first time since Oct. 30, 2010. Woods's girlfriend, Lindsey Vonn, tweeted her excitement.
