Lydia Ko won the ISPS Handa Women’s Australian Open by two shots over Amy Yang. With the win, Ko solidifies her number 1 world ranking, but also managed to claim the top spot in our Power Rankings. I am sure Lydia will mark this as one of her great career milestones (yeah, right).

Lydia only had to move up one spot, displacing Rory McIlroy. McIlroy is scheduled to play the PGA Tour this week at the Honda Classic.  I am sure he will be extra motivated to re-take what was just taken from him.

On the PGA Tour, James Hahn defeated Dustin Johnson and Paul Casey in a playoff at the Northern Trust Open (formerly known as the L.A. Open) for his first victory on the tour. With the win, Hahn rose from 378th to 70th.

And Anirban Lahiri won on the European Tour at the Hero Indian Open (who knew India was in Europe?). It is Lahiri’s second victory this season, and of his career, and moves him to 20th in the rankings.
