Still, there was nothing in Mickelson's words or demeanor that suggested he expected to do anything but just try to make it through the week.
"I'm focused on trying to play well and trying to get healthy to execute the shots I need to execute," Mickelson said. "I'm really not able to think about the results or think about trying to win or top-10 or make cuts or anything like that. That's not really in my thought process."
Mickelson said his wrist had prevented him from putting in the necessary practice and preparation time. He admitted he would like to sit out another week before returning to competitive golf, but this is the U.S. Open.
Mickelson suffered the injury here during a practice session last month. The number of balls he hit out of Oakmont's unforgiving rough caused inflammation in his left wrist. He withdrew from the Memorial during the first round and dropped out of last week's Stanford St. Jude Classic before the event began.
Mickelson had a cortisone shot last week and said the wrist was starting to feel better. He will wear a brace when he plays. But his concerns once competition begins are getting the distance and accuracy needed with a driver and having to hit full iron shots out of the rough.
"I haven't been able to practice [the driver] as well as go at it 100 percent with confidence that it's not going to flare up again," he said. "But this should not be a long-term problem if I don't aggravate the inflammation, and this unfortunately isn't the best week for that, given my driving history."
He said the last phrase with a grin, but Mickelson and the world know that cost him last year on the 72d hole at Winged Foot. Holding a 1-stroke lead on the tee, Mickelson drove the ball far to the left off a tent, wound up with a double-bogey 6, and lost to Geoff Ogilvy by 1.
"I don't ever want to put it totally behind me," Mickelson said of his 2006 collapse. "I still want to look back on it and recall what happened, because I used that analysis to design a game plan to start driving the ball better. If I just forget about it, I'm not taking advantage of the opportunity to take advantage of some weaknesses and hopefully turn them into strengths."
Mickelson enjoyed a terrific run after the Masters, tying for third place in the Byron Nelson Classic and the Wachovia Championship and winning the Players Championship, and appeared ready to come here as a favorite. But the wrist injury followed, making for limited preparation and an uncertain week.
He hopes it won't be a problem, but he'll take it one day at a time.
"I've been looking forward to getting back here for a year," he said, "and looking forward to getting out here for the last three weeks, and I've been thinking about this event. I'm excited it's finally here. I wish I had one more week of recovery and practice time to prepare properly, but you do the best you can."
