nascarWhat we're watching and why: Plenty of sports in high def today. Of course, there's round three of the PGA Championship at 2 p.m. on CBS. I'll be switching between golf (in standard def, unfortunately) and the Busch Series Zippo 200 NASCAR race from Watkins Glen International in Watkins Glen, N.Y., at 2 p.m. on NBC. If you're into soccer, you can catch Los Angeles at Chicago on HDNet at 8:30 p.m. All times are Eastern.
