PEKIN -- If Tommy Kuhl is going to win the D.A. Points Junior Open, he will have to rally in Thursday's final round at the Pekin Country Club.

The first-round leader from Morton struggled on Wednesday, finishing with a 4-over 76 in the American Junior Golf Association event.

That dropped Kuhl to fourth place with a 144 total, behind Luke Armbrust of Wheaton, Dallas Koth of Bloomington and William Marshall of Elburn, who were all tied for the lead at 2-under 142.

"It was just a terrible round," Kuhl said. "I didn't hit it good all day. I didn't make any putts or put myself in the right places.

"I don't think my mental game was there today, so I didn't deserve to play good. But I'll be back tomorrow to show this course and the field what I've got."

Kuhl was 3-under going into the final two holes, but had a bogey on 17 and a double bogey in 18.

Armbrust had his second straight 71 to grab a share of the lead. But he was not happy with how he finished the round.

"I bogeyed 17 two days in a row, so I was a little frustrated," he said. "But I'm happy to be under par, and just ready to go low tomorrow."

Koth had an even-par 72 on Wednesday after a 70 in the opening round.

"I thought I was going to lose ground," he said. "I made a long putt for a 2 on 17 for a good birdie to just come in at even par."

Marshall finished with a 73 on Wednesday using a borrowed club from Kuhl.

"I broke my driver yesterday," he said. "It cracked on the bottom, so Tommy let me use his old one today.

"It worked OK, but I'm just not used to it. I think I'm going to use it again tomorrow."

The three co-leaders will tee off at noon on Thursday.

In the girls division, Thailand native Kornkamol Sukaree of Huntington Beach, Calif., fired a 7-under 65 on Wednesday to take a nine-stroke lead on the field with a two-day total of 137.

Brianna Bolden of Mokena and Charissa Shang of Calabasas, Calif.. were tied for second with 146.
