Rory McIlroy faces a different set of questions from the last time he played, and he had answers for most of them.
His left ankle, with swelling the size of a tennis ball after he heard it snap while playing soccer with friends in early July, felt fine when he got off the plane and began preparing for the final major of the year. His game is good, and he sees no one reason why that will change when the PGA Championship starts Thursday. One other question was little more tricky.
Who's the best player in the world?
McIlroy is No. 1 in the world ranking. He also has watched Jordan Spieth produce an inspiring year in golf by winning the Masters and U.S. Open, and then coming within one shot of a playoff at the British Open. Spieth has four wins this year, one more than McIlroy, though two of them are majors.
"If you were to go by this year, you would have to say Jordan," McIlroy said. "If you go over the last two years, I would say it's probably a toss-up between Jordan and myself. That's a hard one. Okay, we've got the rankings there, but it's all a matter of opinion."
And what was his opinion?
"I'll tell you at the end of the week," McIlroy said with a smile.
The shine came off golf when Spieth's bid for the Grand Slam ended at St. Andrews. It returned when McIlroy began posting photos and videos last week that indicated he would be playing at Whistling Straits, his first tournament since the U.S. Open.
They face off Thursday afternoon, in the same group with British Open champion Zach Johnson. It will be the third time in the past eight majors that McIlroy and Spieth have played together in the opening two rounds.
It has never received attention like this.
"I think that's just what you guys want to see," Spieth said. "I think he and I just want to go out there and try and win the tournament. We have to beat each other in order to do that, along with … 155 other guys. It's great. We're all very happy to see him back. I'm excited to just share a couple days with Rory, and Zach as well."
McIlroy, the defending champion, said he never targeted the PGA Championship as his return. His test came in Portugal last week when he played – and walked – 72 holes. There was no pain, no swelling. And he knew he was ready.
For all the attention Spieth has earned , McIlroy hasn't been a mere spectator to this sensational season. He has three victories, one of them a World Golf Championship, and he had top 10s in both majors he played.
Still, there is a degree of uncertainty about his game. It will have been 53 days without competition when McIlroy tees it up Thursday.
Expectations haven't changed for Spieth, either. For a guy who just turned 22, he is regarded as a greater thinker.
During his final nine holes of practice Wednesday, he was tossing balls in some quirky spots around the green, even down on the sandy bank of Lake Michigan.
He wants no surprises. He is prepared for a tough test.
At stake for Spieth is an opportunity to be the first player to sweep the three U.S. majors in the same season. A victory would make him No. 1 in the world (provided McIlroy doesn't finish second) and make him the first $11-million (U.S.) man on the PGA Tour.
His first goal is to make the cut.
"I've got some work to do these first two days," Spieth said. "And from there we'll adjust and work our butts off to try and get a third major, which would be a pretty cool place in history."
