MADISON, Wis. (AP) -- Milwaukee Bradley Tech senior James Parker pulled out a 2-0 victory with 11 seconds left in overtime to stun Waupaca senior Charlie Wanty and advance to the semifinal round of the 66th annual Wisconsin Interscholastic Athletic Association individual state wrestling tournament Thursday night.

Wanty (41-6) had moved up a division and two weight classes after winning the Division 2 title at 119 pounds last year. Wanty beat Hartford's Jarid Baumgartner 6-3 before losing to Parker.

"I knew I was better on my feet. I thought I could get him in overtime," said Parker (39-3), who admitted it was his first career overtime match. "I did it. I got the takedown."

Parker also had a close match in the preliminary round, beating New Richmond's Bradley Gartner 4-2.

"I had confidence in myself," said Parker, who didn't appear to have any jitters despite making his state tournament debut. "It's my first time at state. But so far I'm getting it done."

Two returning Division 1 state champions kept alive their bid to repeat. Germantown sophomore Jessie Thielke pinned Merrill's Weston Olung in 4:54. Thielke (41-1) then won by a technical fall over Franklin's Chris Strike to advance to the semifinals at 125 pounds.

Thielke won the 112-pound title last year.

Defending 140-pound champion sophomore Brad Dolezal of Marshfield beat Reedsburg's Brent Landon 4-3 in the prelims and beat Wisconsin Rapid Lincoln's Zak Benitz 8-4 in the quarterfinals to move into the 140 pound semifinals.

Stevens Point senior Ben Provisor had an impressive first day winning on a technical fall in 2 minutes, 7 seconds (16-1) against Kenosha Bradford senior Christian Bridgeman in the prelims and pinning Sauk Prairie senior James Wixom (35-2) in 38 seconds in a battle of once-beaten wrestlers in the quarterfinals.

Provisor (41-1) will meet another once-beaten wrestler in Elkhorn senior Richard Kessler (38-1) in the Division 1 semifinals at 171 pounds on Friday.

Stoughton senior Tanner Klitzke pinned Hamilton freshman Bobby Holzem in 33 seconds in their Division 1 preliminary match to record the quickest pin of the day.

"All you care about the first day is getting the W,' and you want to get rid of any nervousness you may have," said Klitzke, who is making his third trip to state and second appearance in the state semifinals. "It feels good any time you hear your name called out as the winner."

Klitzke held on for a 4-2 victory over Muskego's Tyler Quartullo in the quarterfinals to advance to the state semifinals for the second time in three years.

"It never gets old. But I want to get to the finals," he said, after finishing fifth and fourth in his two previous state appearances. "That's my next goal."

In Division 2 all four returning state champions earned first-round byes Thursday. That included three-time champion senior Nick Hagar of Tomahawk (140 pounds); Port Washington sophomore Alex Dieringer (125), Ellsworth senior Hayden Hauschildt (145); and Portage senior Jake Hohlstein (285).

Hagar is attempting to become only the 10th wrestler in WIAA history to win four State championships. He will compete in quarterfinal action in Division 2 Friday morning.

He won the Division 2 crown at 125 pounds in 2006, at 135 in 2007 and at 140 last year. He enters the meet with a 47-0 mark this season and has not lost a match since his sophomore year while recording a 195-5 career mark.

Dieringer (36-2) won the Division 1 title at 103 last year. He moves down a division and moves up two weight classes.

In Division 3, all three returning state champions earned first-round byes including two-time champion senior Dylan Kansier of North Crawford/Seneca (112); Random Lake sophomore Justin Mudlaff (112); and New Lisbon senior Justin Pollack (125). Kansier (42-2) will vie for his third state title after winning titles at 103 pounds in 2007 and 2008.

There were 23 wrestlers who entered the state tournament with unbeaten records and 22 remain. Beloit Memorial junior Alex Polizzi (42-0) recorded a pair of first-period pins Thursday to improve to 42-0 at 215 pounds in Division 1. He was one of only two unbeaten wrestlers to compete on Thursday.
