Bobby Jones Bracket
• No. 32 Nick Watney def. No. 1 Lee Westwood, 1 up. A three-putt from 18 inches at the 16th green scuttled Westwood, who narrowed the deficit to one after a birdie at No. 14.
• No. 48 Ryan Moore def. No. 49 K.J. Choi, 5 and 4. Choi had a bad day, to put it lightly. He had four bogeys and no birdies over his last nine holes.
• No. 57 Matteo Massanero def. No. 25 Charl Schwartzel, 1 up. The 17-year-old Italian was 2-down after he bogeyed No. 3, but rallied to win when Schwartzel had a bogey at 17.
• No. 9 Luke Donald def. No. 24 Edoardo Molinari, 2 and 1. The difference was in the good holes: Donald had six birdies and Molinari had three, never leading.
Ben Hogan Bracket
• No. 29 Rickie Fowler def. No. 4 Phil Mickelson, 6 and 5. Fowler was under par on eight of his 13 holes to eliminate Mickelson, whose day included just two birdies.
• No. 13 Matt Kuchar def. No. 45 Bo Van Pelt, 3 and 2. Kuchar won the first hole, lost it at No. 4, regained the lead at No. 6 and didn't give it up the rest of the way.
• No. 5 Graeme McDowell def. No. 37 Ross Fisher, 4 and 2. McDowell didn't play especially well (1-under par) but Fisher picked up and conceded at Nos. 11, 14 and 16 to go home.
• No. 44 Y.E. Yang def. No. 53 Stewart Cink, 4 and 3. Yang won the first hole and never trailed, extending his lead to five holes after No. 12.
Gary Player Bracket
• No. 2 Martin Kaymer def. No. 34 Justin Rose, 20 holes. The lone remaining No. 1 seed played 5-under-par golf after the fifth hole, winning the match with a sand save on the second extra hole.
• No. 18 Hunter Mahan def. No. 15 Robert Karlsson, 2 up. After dropping two holes behind through 12, Mahan went 3 under, including a birdie at 18 to advance.
• No. 39 Ben Crane def. No. 7 Rory McIlroy, 8 and 7. Crane was blazing, with five birdies in eight holes, while McIlroy played 1-over-par golf.
• No. 23 Miguel Angel Jimenez def. No. 55 Ryan Palmer, 4 and 2. Hard to imagine Jimenez winning with much less than he gave Thursday. He was 2-over par yet prevailed over Palmer, who was 4 over through 12 holes.
Sam Snead Bracket
• No. 30 Geoff Ogilvy def. No. 62 Thomas Bjorn, 1 up. In probably the tightest match of the day, Ogilvy's biggest lead was his final margin, thanks to a Bjorn bogey at No. 18.
• No. 19 Bubba Watson def. No. 51 Mark Wilson, 6 and 5. Watson won four consecutive holes, 10 through 13, taking advantage of a birdie-less day for Wilson.
• No. 38 Jason Day def. No. 6 Paul Casey, 4 and 2.With six birdies, Day stormed to a 3-up lead over Casey, made it 4-up at the 14th green and coasted.
• No. 22 J.B. Holmes def. No. 11 Ernie Els, 1 up. Els never led in a tight match that was never more than one hole apart. Holmes closed it out with six straight pars.
