Chris Stroud ... This Power Rankings snub has finished inside the top 20 in two of his last three starts and sits 50th in the FedExCup standings thanks to a pair of T3s and seven more top 20s. Tied for ninth at Greenbrier in 2010 and chased it with a T18 in 2011. Currently eighth in scrambling, 13th in one-putt percentage, T9 in three-putt avoidance and 38th in adjusted scoring.
Michael Putnam ... Until recently, he was piecing together a season reminiscent of his rookie year of 2007. Despite 19 cuts made back then, only two went for a top 25 and he failed to retain any form of PGA TOUR status. In what is now his third go-around, he's 18-for-24 with three top 25s, including in his last two starts to climb to 96th in the FedExCup standings.
Tim Wilkinson ... Making his Greenbrier debut, but already knows that a fellow lefty can emerge with victory. In fact, 2012 champ Ted Potter, Jr. has turned The Old White TPC into a personal playground with a T6 in his title defense. But the Kiwi arrives in considerably better form having survived his last five cuts, three of which for a top 25. He ranks 48th in strokes gained-putting and T13 in scrambling.
David Hearn ... First start in four weeks. The Canadian earned the rest following a healthy run that was highlighted by a share of sixth place at THE PLAYERS, his third top 10 of the season. Top 20s at Greenbrier in 2011 and 2012. Ranks 53rd in greens hit and 35th in both scrambling and strokes gained-putting.
Roberto Castro ... The Georgia Tech product has yet to validate a breakout 2013 season during which he logged 13 top 25s, including in each event of the FedExCup Playoffs. However, he really didn't make any waves until a solo second at the Quicken Loans National a year ago last week. If he's going to ride the crest of another swell this time, he can tap into the knowledge gained during a T7 at Greenbrier in 2012 when he closed with a career-tying-low 63. Polished last week's T30 at Congressional with a 70 during which his strokes gained-putting registered 3.346.
