Poulter gives Tiger a new nickname: No. 2

Ian Poulter is flamboyant. From his clothes to his tweets.

Poulter, who lost out on a chance to win the European Tour's season-ending championship in Dubai last weekend when he accidentally moved his ball marker on the green, apparently was chided by Tiger Woods while on the practice green Tuesday at Sherwood Country Club in preparation for this week's Chevron World Challenge.

Poulter responded with this tweet: "Tiger called across the putting green today & said don't you know how to mark ur ball, I said settle down No 2."

Woods, of course, recently dropped to No. 2 in the world rankings after a record run at No. 1.

Let the tournament begin ...
