Harrington at Reno-Tahoe Open, Stableford scoring

Add the score to the list of complicated numbers Padraig Harrington, Justin Leonard, Stewart Cink and others will be calculating along with the elevation changes and gusty mountain wind at the Reno-Tahoe Open.

For the first time since the 2006 International in Castle Rock, Colo., the modified Stableford will be used in a PGA Tour event. The system designed to reward aggressive play awards 8 points for eagle, 5 for birdie, zero for par, and minus 1 for bogey and minus 3 for double bogey or worse.

John Daly, Mike Weir, David Duval, Ricky Barnes, Lee Janzen, Rocco Mediate, Stuart Appleby and Chris DiMarco also are in the event on the edge of the Sierra Nevada while the world's best compete at the World Golf Championships in Ohio.
