1. Dustin Johnson
Best Finish: T28 (2016)
Guess his back is feeling OK. In his first tournament after a month layoff due to an injury that forced him to miss the Masters, DJ was the clubhouse leader on Sunday at the Wells Fargo Championship up until Brian Harman nailed a 28-foot putt to grab the win. Though Johnson "only" finished tied for second, he proved that he's perfectly healthy. And that's all that's important.
The World No. 1 has been historically mediocre at the Players with zero Top-25's in eight starts, but someone who tallies five Top-10's in a row--and when he wins three straight in the middle of that--has to be the No. 1 favorite. That's a rule. (Getty)
