Wichita State sophomore Hunter Sparks shot 3-under 67 to take the lead Tuesday following the opening round of the 100th Kansas Amateur at Prairie Dunes in Hutchinson.
Sparks and Wichitan Charlie Stevens were the only players in the field of 156 to break par. Stevens shot 1-under 69.
Sparks, from Oklahoma City, teed off early in the day and started on the back nine. He had six birdies during his round.
"I hit the drives really well — I stayed out of the tall native grass which you have to do around here," Sparks was quoted as saying on the Kansas Golf Association website.
"I found something in my swing earlier this week and started hitting hit pretty good so I knew I had a chance. I didn't think 67 was out there."
The 40-year-old Stevens, who also had a morning tee time, had an eagle on the par-5 seventh hole, and finished his round with birdies on 17 and 18.
"It's a tough course and you've got to putt well and I really putted well today," Stevens said on the KGA website.
Five players were at even-par 70, including two-time champion Bryan Norton of Mission Hills. Only one of the top seven golfers teed off in the afternoon — Zac Burton of Manhattan.
The Amateur continues with another round of stroke play today. The top 64 players after the second round qualify for match play starting Thursday. The 36-hole match play championship is scheduled for Sunday.
