If Chris DiMarco keeps playing like this, his 14-year-old son may have landed a permanent job as his caddie. The three-time winner on the PGA Tour who hasn't finished in the top 10 since 2008 shot a 5-under-par 67 with Cristian DiMarco on his bag for the first time at the Reno-Tahoe Open on Thursday, good enough to be a stroke behind first-round leader Matt Bettencourt.
