AKRON, Ohio — Rory McIlroy has sponsors logos on his sleeves. He doesn't want his emotions there as well.
After what has been an erratic year of great victories and dismal defeats, he's trying his best to internalize his feelings a little bit more on the course.
In other words, fewer grimaces and grins, more focus, less frustration.
"I've become a little bit too emotionally involved with my golf over the last few months, I guess," he said Wednesday, a day before the start of play in the Bridgestone Invitational. "I've let it either get me excited or get me down, where I should really just not get too high or too low about it at all."
In the glaring light of worldwide golf acclaim, McIlroy's temperament is a focal point. It's certainly not difficult to tell from a quick glance how things are going for the 24-year-old from Holywood, Northern Ireland.
By most any measure, his last year has been very successful. He won the 2012 PGA Championship at Kiawah Island, and will defend next week at Oak Hill. After winning his second major, he had back-to-back victories at the Deutsche Bank and BMW Championship late in 2012, giving him four wins on the year. After that, he played an integral part in Europe's stunning come-from-behind win over the United States in the Ryder Cup.
This calendar year, he hasn't won on the PGA Tour, hasn't really threatened in the three majors (a missed cut at the British Open, a tie for 41st in the U.S. Open and a tie for 25th at the Masters) and has one top-five finish in 11 starts. On the European Tour, he has only finished in the top 10 in one of his eight starts.
There have also been a couple of public meltdowns. He withdrew at the Honda Classic because of poor play. His mental state was called into question by the British tabloids after he expressed his frustration two weeks ago after two bad rounds at Muirfield.
