AVONDALE, La. --- Charlie Wi shot 6-under-par 66 to take a one-stroke lead Thursday in the first round of the Zurich Classic as Kenny Perry returned to action.
Perry, playing for the first time since losing the Masters Tournament in sudden death, shot 69.
Perry parred his first six holes, had five birdies on the next six, then had bogeys on 15 and 17.
"I need to kind of get back in the thick of a tournament," Perry said. "I really felt good out there today. I did lose focus a little bit and kind of think a lot about two weeks ago, what was going on, but I mainly got tired. I mainly got tired mentally, which got me tired physically."
The 48-year-old Perry said he had a headache by the time he finished and wanted to get a good meal and a good night's sleep.
Perry, who led the Masters by two strokes with two holes remaining only to lose in a playoff, said he had considered skipping the event, but has always played well in New Orleans and wanted to get back in action to put the Masters loss behind him.
Wi's 66 was two strokes short of matching the course record at the TPC Louisiana.
"On the weekend the golf course gets so difficult. So to shoot a good number on Thursday and Friday, I think it really helps you to have a high finish," Wi said.
Jay Williamson, Nathan Green, Parker McLachlin, Charles Warren, John Merrick and Eric Axley opened with 67s.
Augusta native Charles Howell shot 68.
Danny Lee had a triple bogey on No. 4 and shot 76 in his pro debut.
