It's not summer vacation for Dingus, like it is for most college golfers. He attends Palmer College of Chiropractic, where classes are held year round. But it doesn't appear to be affecting his golf game.

Dingus started strong at Southern Hills Plantation, going 3-under for his first six holes. He bogeyed No. 8, turning at 2-under par. Playing consistently throughout the back nine, the former Stetson Hatter parred his first five holes of the back nine before carding his fourth birdie of the day on the 385-yard, par-four 15th hole.

Standing on the 18th tee, Dingus was 3-under on the day, but drove it out of bounds. Forced to retee, he made a "second ball birdie" that must have felt especially nice on No. 18, as it preserved an even par score on the back nine and secured the top seed.

 "It was the most stress-free round I've ever played," Dingus said, perhaps having already forgotten that O.B. shot on No. 18. "It was nice getting back out there after being in school all day."

Three players trailed Dingus at 1-under, including 2015 Amateur Match Play Champion, TJ Shuart, of Fort Lauderdale. Shuart, a past champions of the Coleman Invitational, along with Kasey Denesevich and Marc Dull will enter match play as three of the four top seeds. The defending champion, Christopher Carlin sits just outside the top four after shooting an even-par round of 72. Carlin is in a five-way tie for 5th.

The first round of match play will take place tomorrow morning, with Round-of-32 matches starting immediately following play.

And thanks to that bogey save on No. 18, Dustin Dingus will get the morning off as he earned himself a bye from the first round and will not have to tee it up until the afternoon.
