Pool play
Players were divided into 16 groups of four players and played round-robin matches on Wednesday to Friday.
- Round 1 – April 29
- Round 2 – April 30
- Round 3 – May 1
Notes: Round 1
Of the 32 matches played, 14 were "upsets" with the lower seeded player beating the higher seeded player. These included #3 Henrik Stenson (lost to #60 John Senden), #6 Justin Rose (lost to #56 Marc Leishman), #7 Jason Day (lost to #49 Charley Hoffman), and #9 Adam Scott (lost to #64 Francesco Molinari).[8]
Notes: Round 2
Of the 32 matches played, 16 were upsets. These included #5 Jim Furyk (lost to #44 Thongchai Jaidee), #7 Day (lost to #38 Branden Grace), #8 Dustin Johnson (lost to #37 Charl Schwartzel), #9 Scott (lost to #36 Paul Casey), and #10 Sergio García (lost to #39 Bernd Wiesberger). Two players, #13 Rickie Fowler and #60 John Senden, were guaranteed to advance.[9][10]
Notes: Round 3
Of the 32 matches played, 18 were upsets. These included #2 Jordan Spieth (lost to #26 Lee Westwood), #3 Stenson (lost to #23 Bill Haas), #4 Bubba Watson (lost to #29 Louis Oosthuizen), #7 Day (lost to #24 Zach Johnson), #9 Scott (lost to #25 Chris Kirk), and #10 García (lost to #30 Jamie Donaldson). Day, Scott and Jimmy Walker were the only top seeds to lose all three matches. Only five of the top seeds advanced: #1 Rory McIlroy, #5 Furyk, #12 J. B. Holmes, #13 Fowler, and #16 Hideki Matsuyama. 12 of the 16 group winners advanced with perfect 3–0 records. Three groups winners advanced based on head-to-head tie-breaker and one group went to a three-way sudden-death playoff. Branden Grace defeated Zach Johnson and Charley Hoffman on the third extra hole in group 7. In Group 11, all six matches of the three rounds were upsets. A total of 18 of the 96 matches went extra holes, causing some to suggest altering the format next year to include halved matches.[11][12]
