The top players in the world are at the WGC-Bridgestone Invitational this week so the Reno-Tahoe Open will give some of the PGA Tour\'s big hitters a chance to shine. Former winner John Rollins, Billy Horschel, JB Holmes and John Daly will be teeing it up at the $3 million event this week that will be contested using modified stableford scoring. Rollins is ranked second in total driving and Holmes is fifth in driving. Under the stableford system, points are awarded for your score on hole. Eight points are given for a double eagle, five for an eagle, two for a birdie and zero points for par. A player will lose a point for a bogey and three for double bogey or worse. Defending champ Scott Piercy is not playing after having won the Canadian Open last week, which qualified him for the Bridgestone. But the tournament got a boost when three-time major champ Padraig Harrington joined the field. Harrington said he needs the extra work to get ready for next week\'s PGA Championship. Harrington will play in a threesome with Stewart Cink and Brian Gay. Daly and Holmes will be joined by Craig Barlow. Rocco Mediate, Camilo Villegas and Justin Leonard make up another strong trio.
