DirecTV's HD Mix extended to cover the entire U.S. Open weekend

The U.S. Open gets started tomorrow from Bethpage State Park, and beyond the ESPN & NBC coverage, DirecTV is extending its HD Mix channel for all four days for the first time. That should help keep an eye on the leaderboard, main broadcast and whatever combination of specific areas of the course, interviews, or particular golfers one wants to follow, all available in high definition of course. After the Mediate/Woods showdown last year, we hope they're not locked in to doing only four days of broadcasts.
