Match 2: Jon Rahm (21) def. Soren Kjeldsen (62), 7 and 5: A perfect 5-0 this week, Rahm has won his last three matches 6 and 4, 6 and 4, 7 and 5. He went 1 up through one in the quarters and needed only 13 holes before Kjeldsen conceded. Rahm has lost one hole in his last three matches.
Match 3: Bill Haas (42) def. Phil Mickelson (14), 2 and 1: Haas won the opening hole and was 3 up at the turn before Mickelson started to chip away. Lefty cut his deficit to 1 down but could get no closer. Haas extended his lead back to 2 up on the 15th and closed out Mickelson with a two-putt par on 17. For his efforts, Haas gets the red-hot Rahm.
Match 4: Dustin Johnson (1) def. Alex Noren (8), 3 and 2: Johnson saw a 3 up lead evaporate in three holes when Noren took Nos. 10-12. But birdie putts from Johnson at 13, 15 and 16 pushed Johnson through to the final four. He'll take on Tanihara on Sunday morning.

ROUND OF 16
Match 1: Bill Haas (42) def. Kevin Na (46), 1 up: Na was 2 down after 12 holes, but he made two straight birdies to square the match heading to the par-4 15th. Both players missed the green, but Haas was able to get up-and-down for par to regain the lead.
Match 2: Phil Mickelson (14) def. Marc Leishman (28), 4 and 3: Lefty was 5 up after 10 holes, but Leishman briefly bounced back with wins on 11 and 12. Mickelson closed out the match after Leishman made a mess of the par-4 15th.
Match 3: Jon Rahm (21) def. Charles Howell III (61), 6 and 4: A day after beating Sergio Garcia, 6 and 4, Rahm did the same thing to Howell. The 22-year-old Spaniard was 2 up after three holes and never looked back as he closed out the match with a birdie on the par-4 14th.
Match 4: Soren Kjeldsen (62) def. William McGirt (48), 5 and 4: Kjeldsen had the day off on Friday after Gary Woodland withdrew, and he didn't show any signs of rust against McGirt. The Dane went 3 up thru 9 when McGirt made two straight bogeys, and Kjeldsen secured the win with a birdie on the par-4 14th.
Match 5: Hideto Tanihara (54) def. Paul Casey (12), 2 and 1: Tanihara never trailed in the match and continued his surprising run into the quarterfinals with birdies on 16 and 17 to beat Casey.
Match 6: Ross Fisher (47) def. Bubba Watson (13), 4 and 3: Fisher was 1 down after seven holes, but Watson made two straight bogeys to hand Fisher the lead heading to the back nine. Fisher was solid the rest of the way and finished off Watson by holing out from a greenside bunker at the par-4 15th.
Match 7: Alex Noren (8) def. Brooks Koepka (20), 3 and 1: Koepka had the momentum heading into his match against Noren, but the Swede took the lead early and never trailed. After Koepka hit his tee shot into the hazard at the par-3 17th, Noren closed him out with a laser to 3 feet.
Match 8: Dustin Johnson (1) def. Zach Johnson (44), 5 and 4: The No. 1 player in the world continued to play like he's the man to beat. DJ won the first hole, was 4 up after nine holes and easily won with a birdie on 14.
