Don't know if pairings are out yet, or if this is right, but the last four pairings should be:
Riley-Olgivy
Woods-Love
Herron-Donald
Stenson-Andrade
Woods-Love have played together in the Ryder Cup, and should be fun to watch. Herron-Donald likely sets a record for thickest-thinnest combo in a recent major.
Say what you will about the course and the proliferation of under-par rounds, it's producing a pretty interesting leaderboard. Four-way tie, Tiger and Ogilvy a stroke back, and lots of good lurkers -- Sergio, Toms, Weir, Lefty, Scott, Olazabal -- not that far back. Plus some good stories in the likes of Mayfair and Funk, and the Ryder Cup backdrop. Should be a fun weekend.
