Garcia also said he tweaked his back on a tee shot at the 10th and would get treatment on it, uncertain he would play depending on how it felt Saturday.
Through it all, there was plenty of aggravation. Bubba Watson opened with a three-putt from 10 feet, added a four-putt from about 65 feet on the 12th hole, and had another three-putt from 15 feet.
But it was like that for everyone, which is why McNeill had a peculiar answer when asked what the winner had to do well this weekend.
"It's the guy who keeps control of his emotions the best," McNeill said. "The greens will have an effect on you. You've just got to keep positive. You're going to have good putts that miss, and you might have some bad putts that go in."
Mickelson is less concerned with his run of amazing putting than with getting the ball in play. He has hit only 11 fairways going into the weekend, though he found something in his alignment early on the back nine and was hitting it where he was aiming the rest of the way.
"It's fun to be in contention. It's fun to be in the mix," Mickelson said. 'It's great to be leading, but we're only halfway home. There is a lot of golf left. I have to come out and play very well. But I've been putting very well this week, and I've been driving the ball very well before I got here. And I think if I drive the ball the way I've been before I got here, and not the way I did the first few days, I think it's going to be a fun weekend."
