Another stomach-turning, six-round session of PGA Tour Q-School is in the books, with Pro V1x loyalist Richard H. Lee the most likely poster boy from this year's graduating class.

Lee, a former All-American at the University of Washington, played his final five holes in 5-under-par Sunday afternoon at PGA West, rolling his Pro V1x golf ball in for birdies on Nos. 17 and 18 to secure his 2012 PGA Tour card by a shot.

On 18, Lee (pictured, inset) hit his approach from 142 yards directly into the blaring sun, toward a green guarded by both water and bunkers. He blocked the rays with his right hand as his Pro V1x landed on the front of the green, bounced once and checked up 7 feet from the hole, leaving him just two putts from one of the best jobs in golf. He only needed one.

Such dramatics are a constant every year at Q-School. As are Titleist equipment players at the top of the leader board.

Twenty of the 27 players that earned 2012 PGA Tour cards trusted Titleist golf balls for their success, including Q-School medalist and Pro V1x loyalist Brendan Todd, who closed with a 4-under 68 to shoot a six-round total of 17-under 415.

Titleist Brand Ambassadors Bobby Gates (T-3), Jarrod Lyle (T-5), Will Claxton (T-18) and Mark Anderson (T-24) all earned full playing privileges next season trusting Pro V1x golf balls, Titleist 910 drivers and fairways metals, 712 Series irons, Vokey Design Spin Milled wedges and Scotty Cameron putters.

As for victory celebrations, look to Lyle and fellow Pro V1x loyalist Vaughn Taylor, each of whom tied for fifth to earn their return trips to the PGA Tour.

Lyle is getting married Saturday in Australia. Taylor's scheduled to tie the knot Saturday in the Bahamas.

Of the 173 players at the final stage, 121 played a Titleist golf ball, more than seven times the nearest competitor with 16. Titleist was also No. 1 in Iron Sets (49), Putters (53) and Sand, Lob and Approach Wedges (150).
