At the risk of everyone taking their favorite Hanse(o)n, Furyk, Mahan, and Villegas, I think the smaller groups mean we(everyone not named hoopinion) might actually win one of these. Also, one of those players may or may not be in the field.
Those came straight from pinnacle, as did most of these match-ups(I made up the last two based on proximity in my rankings). All for one point:
Steve Stricker v. Hunter Mahan
Stewart Cink v. Geoff Ogilvy
Ernie Els v. Vijay Singh
Aaron Baddeley v. Andres Romero
Zach Johnson v. Ian Poulter
Steve Flesch v. Trevor Immelman
Ross Fisher v. Henrik Stenson
Phil Mickelson v. Jim Furyk
Sergio Garcia v. Camilo Villegas
Remember, pick a winner in each group, and four match-ups with one double, and INCLUDE YOUR TEAM NAME in the entry. Saves me a lot of time.
