Once upon a time, Hunter Mahan was your lock for the Travelers Championship. From 2006-2009, he won once, finished second twice and added a T4. Therefore, it should come as no surprise that he's the all-time money leader of the event with over $2.4 million.

If he's dropped on your short list at TPC River Highlands, it's with good reason since he has failed to add a top 10 since. However, he capped a T11 last year with a career-low 61. He's also coming off a share of fourth place at the U.S. Open. That's good for his best finish in a stroke-play event all year. That's also good enough for me. Mahan is my play.

This is also a fine site for 2010 champ Bubba Watson. He's third on the tournament's money list with five cuts made. His record includes a T6 in 2008 and a co-runner-up last year. If Mahan weren't available to me, I'd burn the lefty right now.

Stewart Cink (fourth in all-time money) and Ryan Moore (fifth) are solid complements in two-man formats. Moore will rise into focus again later.

If you wanted to swing for the fences, pencil in John Rollins, who sits sixth in my Power Rankings. He's in tip-top form and has a pair of top fives at the Travelers Championship the last two years.

Tim Clark

After a six-year hiatus preceded by an 0-for-3 slate at TPC River Highlands, he returned in 2012 and finished with a share of fourth place. For the week, he ranked T10 in greens in regulation, first in proximity to the hole, second in scrambling, T7 in par-3 scoring and T2 in par-4 scoring. Arrives having missed his last two cuts, but both opportunities were undone by second-round 79s. Three top 10s and another two top 25s on the season. He's 45th in adjusted scoring and 42nd in FedExCup points.

A wide-open U.S. Open is nothing new, and its intention remains to identify the best golfer of the week -- no doubt, it will achieve that as usual -- but one-and-doners can focus on a short list.

For whatever reason, multiple followers of mine on Twitter were surprised that Graeme McDowell sits atop the Power Rankings. The consensus was that the 2010 U.S. Open champion, winner of two of his last four starts entering this week, wouldn't be on most radars. Well, if he were available to me, he'd be my selection at Merion. (I exhausted him at the World Golf Championships-Cadillac Championship, where he tied for third.

In fact, I've burned all of my top four. Adam Scott sits fifth and he's still on my board, but I'm saving him for the FedExCup Playoffs. So, I'll go with an old standby at the season's second major, Lee Westwood.

In addition to his run of fortune at the U.S. Open in recent years, the Englishman has performed very well of late. Moreover, ball-striking (and potentially power) will be at a premium and relatively unknown greens could benefit average putters. And while it doesn't influence my strategy, it's worth noting that the U.S. Open is his first as a 40something.

Louis Oosthuizen

Available to compete because his third child was born early. The due date was Saturday, June 15. Prior to welcoming daughter No. 3 into the world, he was beset by a neck injury that forced him to withdraw during the HP Byron Nelson Championship, and then early from his next two scheduled commitments. Had posted three top 20s in his previous four starts. If he were eligible for official rankings, he'd sit 15th in greens in regulation, third in scrambling and 59th in adjusted scoring.

If you've been waiting for an opportunity to go off the board, then the FedEx St. Jude Classic presents a golden opportunity.

Taking a peek at my Power Rankings, Brandt Snedeker (No. 1) and Charles Howell III (No. 2) are chalk choices, but this event barely cracks their personal top 20s among tournament earnings. It's yet another reason to roll the dice on a hot hand.

This is why I'm burning Scott Stallings. He's coming off back-to-back fourth-place finishes. He also played well enough at the U.S. Open sectional qualifier in Memphis on Monday to nab first-alternate status before getting into the field at Merion when Roger Chapman withdrew on Tuesday.

Stallings is making his third appearance at TPC Southwind, where he tied for 25th in his first in 2011. He also went to high school and college in Tennessee and still resides there. State pride cannot be quantified, but pursuit of it should not be ruled out.

If you're looking for someone with more wattage, the deeper you get into the top 20 in earnings at this tournament, the more attractive your choices become. Robert Karlsson ranks 12th; defending champion Dustin Johnson is 13th; and steady Freddie Jacobson sits 16th. All demand our attention unless, of course, your format excludes defending champions. Even John Merrick at 19th plays into the hands of two-man games.

Billy Horschel

It's not unusual for a guy trending strongly who then breaks through to experience a rapid decline. His win in New Orleans capped a run of four consecutive top 10s, but he's gone 1-for-2 since with a T41 at the Memorial. Given the dynamics and field depth of both events, the timing could be coincidental, but he also carded three rounds of 75 or higher in his last six rounds. Nevertheless, I'm giving him the benefit of the doubt due to impressive form otherwise, he's a great fit for TPC Southwind. Ranks 29th in fairways hit, T30 in greens in regulation, 16th in strokes gained-putting and 15th adjusted scoring. This is also his fourth appearance, so he should know his way around the property.

If Tiger Woods is still available to you and your format doesn't exclude or limit usage of defending champions, then he's the play this week. The only reason you wouldn't plug him in is because you're waiting for the World Golf Championships-Bridgestone Invitational since it rewards more prize money and FedExCup points. However, Woods would still need to win there to outperform a win at the Memorial Tournament presented by Nationwide Insurance.

There's also a strategy that warrants holstering him until the TOUR Championship by Coca-Cola, but it may not matter to you; that is, if you're mathematically eliminated by the finale. With five victories and another three top-four finishes at Muirfield Village converging with four victories already this season, including in his last start at THE PLAYERS Championship, it's nearly impossible to win the alternative argument.

Each of the top nine in all-time earnings at the Memorial are in the field this week -- No. 10 Steve Stricker is the only absentee among the top 14. We can immediately discard Kenny Perry (second), Fred Couples (sixth) and Vijay Singh (eighth) for the purposes of this week's discussion.

The 2002 champion, Jim Furyk, sits third, and deserves a long look. If you're not tempted this week, you know he'll want redemption at the U.S. Open (in his home state no less), so consider using the Memorial as a watch-and-see opportunity. A start at East Lake would also make a ton of sense, but he has to qualify first.

Justin Rose won the Memorial in 2010 and ranks fourth in all-time earnings there. He's also banked more at this tournament than any other on the PGA TOUR. His streak of consecutive top 25s came to a screeching halt with a missed cut at THE PLAYERS and a tie for 50th at the BMW PGA Championship, so there's reasonable concern if he's your one-and-done selection.

K.J. Choi (seventh in all-time earnings) and Stewart Cink (ninth) are suitable choices in two-man formats. This is arguably your last most logical site to use Choi. Cink presents a safe horse-for-course angle for a guy that has enjoyed a rebound this season.

The man missing from the top nine above is my choice for the Memorial -- Ernie Els. Fifth in all-time earnings, his recent record at Muirfield Village will turn off many as he's posted just one top 50 in his last five appearances (T8, 2009). However, he's put together a number of quietly strong outings over the last two months, including a 13th at the Masters and a sixth at the BMW PGA Championship.

Unless your format would allow for a potential start at The Open Championship where he will be defending, it's likely he won't again emerge as a candidate until the Playoffs.
