A morning storm delay led to the first round being halted by darkness with 30 players from the field of 156 being forced to finish their opening round on Friday.
Garcia finished early while Lee was among the late finishers and Wagner made his final putt in twilight. All three started on the back nine and went bogey-free.
It was a great time for Garcia to find his form with the US Open only a month away.
“I’ve been playing decent and obviously I still feel like I can play better,” Garcia said. “Hopefully I can keep this momentum going and have a good solid week before the US Open.”
Garcia sank a 17-foot birdie putt at the 15th hole to make the turn at one-under. At the par-3 second, he landed a tee shot three feet from the cup and made the birdie putt.
After adding a five-foot birdie putt on the fouth hole, Garcia ran off a 26-foot birdie putt at the sixth, eagled the par-5 seventh from 58 feet and followed with a 10-foot birdie putt at the eighth hole.
“I had a couple of pretty nice saves and I really got going on the (second) nine,” Garcia said. “I made a couple of bombs out there and that really helped.”
South Korean-born Kiwi Lee, who won his first PGA event at last year’s Greenbrier Classic, began his round with three birdies, the last of them from 21 feet.
