October 15, 2009 (Updated 10/16) --The Justin Timberlake Shriners Hospitals for Children Open is in full swing, so to speak, and golfers are still going way low, despite the PGA Tour changing the third hole at Las Vegas golf course TPC Summerlin from a par 5 into a par 4 for this year's event. Veteran Tom Pernice, Jr. and former Las Vegas champ Troy Matteson are the current leaders, recording rounds of 9-under par 62 while Las Vegas' Scott Piercy fired a 64 as did 3-time Las Vegas champ Jim Furyk (Spencer Levin also came in with a late 62). Piercy spent nearly as much time watching his phone as he did his golf ball because his wife is expecting a child at any moment. It's still up in the air what Piercy will do when and if she goes into labor this weekend. "I told her I will do whatever she wants," said Piercy, who grew up in Las Vegas and played junior and high school golf here.  Click now for up-to-minute LIVE SCORING.
