MIAMI – Connor Peck saved the best for near the last.
Peck, a former Kansas Jayhawk who was playing in one of the dayâ€™s final groups, shot a 9-under 63 to take the first round lead at the Buffalo Run Casino Classic.
Oklahomans held seven of the top 42 positions in the Adams Tour stop at Peoria Ridge Golf Course.
Peck, from Ankeny, Iowa, held a one-stroke lead over Hunter Sparks of Oklahoma City and former Oklahoma State star Edward Loar of Rockwall, Texas.
Peck had birdies on No. 1 and 2 and 8 and 9 on the front side, then rattled off three straight on 12, 13 and 14, parred 15 and 16, then finished with birdies on 17 and 18.
Peck finished 10th at the Big 12 Tournament last month. He had six top-10 finishes for the Jayhawks this season.
He missed qualifying for the NCAA Tournament by one stroke.
Sparks and Loar each had rounds of 8-under 64 and held the lead ever so briefly.
Loar wasnâ€™t surprised at Peckâ€™s round.
â€œI have played enough golf where nothing surprises me any more,â€ Loar said. â€œObviously I played well. I probably made more putts than I have all year. There are so many good golfers now that somebody is going to have a hot day or a hot week. When you get one of those opportunities, you better keep going.â€
He logged seven birdies and had an eagle on the par-4 17.
â€œMy putter was pretty hot,â€ Loar said.
Sparks, a former Wichita State standout, had eight birdies, including five on the front nine.
This is his third tournament of the season.
â€œI made some pretty good putts,â€ he said. I missed probably a 5-footer coming in and then I didnâ€™t birdie 17, being just long of the green.â€
Peck, Sparks and Loar were part of an afternoon at Peoria Ridge Golf Course that featured 92 degree temperatures and a heat index of 109.
Conditions are expected to remain the same through Saturdayâ€™s final round, with highs of 96 Thursday, 95 on Friday and 94 Saturday.
