A superb second round -6 under par 64 gave Sergio his breathing space at the half-way stage of the tournament at Cherry Hills Country Club, posting a tournament total of -8 under par. A pulled second shot into the par five 17th, which ended in the lake, was rescued with a one putt par. He was bothered by a strange medical condition with his left ear, but it clearly didn't affect his golf; "It's happened before, but usually I kind of blow it and it gets back, but for some reason, it just didn't feel quite the same. And it still doesn't, but it's definitely better. It shouldn't be too big of a deal." "Obviously, it helped, because then I made 2 on the next hole." "It's only Friday, so we still have two days to go, but it definitely helped my frame of mind going into the 18th tee, which today was playing quite hard. So it was nice to be able to get that up-and-down and then play 18 really well." “After a couple weeks where I didn't play my best, and I didn't feel quite that comfortable, it's nice to at least put two solid rounds together here. I'm looking forward to playing well on the weekend, too. And then, obviously, get ready for the Ryder Cup.” Ryan Palmer is alone in second spot, just one shot behind at -7 under par, a late run of birdies, on 13, 14 and 17, 18 helped him to his -6 under par 64. He thought the rains had made the greens softer, and more accessible and he was right; "It was a great way to finish, I was glad I was one of the ones that shot low." Rory McIlroy and Billy Horschel are tied in third place at -6 under par. Rory was not too happy with his round overall, but was happy to birdie three of the last four holes; "I feel much better coming off the golf course because I birdied three of the last four holes. I sort of struggled to get anything going today. It was a little cooler, so the ball wasn't going quite as far, a little bit of wind, even though the course was softer, it still played pretty tough." Phil Mickelson is probably playing his last PGA TOUR event of the season, he needs to finish about fourth to qualify for the TOUR Championship but is 14 shots behind and in a tie for 63rd in the 68-man field. Jason Day had to retire on the ninth hole, citing a back injury, but hopes to be ready for the TOUR Championship.
