Throughout the 2009 season, Yahoo! Sports golf editor Michael Arkush presents his power rankings, breaking down golf's best and brightest. Wins count, but so does competitiveness and potential. Your latest rankings:

1: Tiger Woods: He's back and just in time to defend his Open crown. Put it this way: If he hits 49 of 56 fairways at Bethpage, it will look like Pebble Beach in 2000 when he won by 15 shots. When will we stop doubting him? Glad I wasn't one of those skeptics.

2. Phil Mickelson: Lefty is sure to be rusty this week in Tennessee, but look out for him to make a serious run at Bethpage, where he played extremely well in 2002. The crowd certainly will be on his side more than ever, which should be an enormous benefit.

3. Steve Stricker: We're on to you. All you're trying to do is secure your third Comeback of the Year award in four seasons. It won't work. Keep it up, though, – four top 10s in your last seven starts – and you just might snag Player of the Year.

4. Zach Johnson: He failed to break 70 in four days at the Memorial, but was on quite a roll throughout May, with three top-11 finishes in four appearances. The idea of him being a one-hit wonder in the majors (2007 Masters) is beginning to look premature.

5. Jim Furyk: Take out the MC at Hilton Head nearly two months ago, and Furyk has gone T10, T11, T5, T9 and then second last week to Woods at the Memorial. Yet he's winless since the Canadian Open in July 2007. To say he's due is a huge understatement.

6. Sean O'Hair: Forget about the WD at Jack's tournament. Prior to last week, O'Hair had compiled four top 10s in eight starts, including an impressive victory in the Quail Hollow Championship. His next challenge: To contend on Sunday afternoon in a major.

7. Paul Casey: Now that he's finally picked up that first victory in the United States, look out for Casey to add a bunch more. He hasn't missed a cut in seven starts, and at 31, just might be the most overlooked young talent in the game.

8. Geoff Ogilvy: Granted, Ogilvy has only one top 10 since Augusta, and that came last week. Yet he's only played four times since the Masters and is one of only four players to have notched two victories this season.

9. Ian Poulter: Poulter was quite unimpressive at the Memorial, but put together a lot of solid weeks during April and May, continuing to feed off his wonderful showings in last year's British Open and Ryder Cup.

10. Tim Clark: Clark was in great position to post his first tour victory until he stumbled down the stretch a few weeks ago at Colonial. He is too steady a player to go winless for very much longer.
