Pro V1x loyalist Jonathan Byrd may have made the ace of the week – if not the year, decade, or even century – Sunday in Las Vegas as darkness fell on the Justin Timberlake Shriners Hospitals for Children Open. (It marked the first time a PGA Tour event has ever been decided by a hole-in-one.)

But there was another "1" last week at TPC Summerlin that was comparable, at least in terms of obstructed views.

During Thursday's opening round, Titleist Brand Ambassador Webb Simpson stepped to the tee at the 231-yard 8th hole, the longest par-3 on the course, and pulled from his bag a brand new 21-degree Titleist 910H hybrid with the SureFit Tour hosel in the B2 position (+0.75 upright, standard loft) and a Graphite Design Tour AD shaft, which he had been fit for just a day earlier. (He also carries a new 19-degree 910H hybrid in his bag.)

Webb teed up his new Titleist Pro V1x prototype golf ball – which he's used to finish T-12, T-44 and T-4 the last three weeks and help secure his 2011 PGA Tour card – then sent it soaring just a touch right of the flag.

It landed about 7 feet in front of the pin, hopped once and rolled into the cup (check out the video below). Webb knew he'd hit a good shot, but started walking to the green with his putter in hand, a blind angle to the pin delaying the celebration for a minute or two.

"One of the Titleist guys fitted (the 21-degree 910H) for me perfectly," he said after the round. "Just a good (yardage). Looked good... We didn't know it went in until we went to the green."

Three days later, fading sunlight would keep Byrd from watching his Pro V1x's historic journey into the hole at the 220-yard par-3 17th.

When Webb and his caddie finally realized the ball had gone into the hole, they celebrated with a chest-bump in the fairway.

"Yeah, it was a good feeling," he said. "I saw the ball mark couple feet short and I knew it was in."
