If the Texas Open winner is not already in the field, he'll get a spot in The Masters. Otherwise, the 2013 Masters field was set on Sunday.
And if that's the case, then the last four golfers to get in were D.A. Points - winner of the Shell Houston Open - plus Henrik Stenson, Fredrik Jacobson and Richard Sterne.
Points had to have the win to get in, because even with it he only rose to No. 70 in the world rankings. All golfers in the Top 50 after the Houston Open received Masters invites, and that's the route Stenson, Jacobson and Sterne took to Augusta National.
Who's left on the outside looking in at the Texas Open? There are five major champions playing in San Antonio this week who have to win to get into The Masters: Retief Goosen, Geoff Ogilvy (update: Ogilvy withdrew) and Justin Leonard, plus John Daly and David Duval.
A couple guys to keep an eye on: San Antonio residents Jimmy Walker and Cameron Beckman, plus 19-year-old phenom Jordan Spieth.
Some of the other notable players in the Texas Open field who have to win to get into the Masters include: Robert Allenby, Stuart Appleby, Aaron Baddeley, Ricky Barnes, Jonathan Byrd, Chad Campbell, Bob Estes, Tommy Gainey, James Hahn, Charley Hoffman, Robert Karlsson, Martin Laird, Shane Lowry, Seung-Yul Noh, Jeff Overton, Ryan Palmer, Andres Romero, Heath Slocum, Kyle Stanley, D.J. Trahan and Scott Verplank.
