FORT WORTH, Texas -- Graham DeLaet, the Canadian looking for his first PGA TOUR win, finished his front nine in Saturday's third round with a two-shot lead at the Crowne Plaza Invitational at Colonial.

DeLaet is a bogey-free 2 under on his round and is now at 11 under.

Six players were tied for second at 9 under when DeLaet made the turn.

Matt Kuchar, the 36-hole leader, opened with a birdie the par-5 first but suffered consecutive bogeys at the seventh and eight holes to drop out of the lead. Kuchar had bogeyed just one hole in the first two rounds.

Jordan Spieth, the 19-year-old from Dallas, was also part of the large group at 9 under. Spieth had grabbed the lead earlier in his round after a birdie at the par-4 fifth, but suffered bogeys at the sixth and ninth holes.

Steve Flesch, the 2004 Colonial champ, had moved to 10 under before finding trouble at the ninth when his approach shot found the water guarding the green.

Martin Flores has the best round going among the contenders. Flores is 5 under through his first 16 holes to move to 9 under.

Matt Every and Freddie Jacobson also are at 9 under.

Defending champ Zach Johnson is 2 under on his round and 8 under overall.

FORT WORTH, Texas -- Jordan Spieth, the 19-year-old from Dallas, birdied the par-4 second hole after hitting his approach shot from 100 yards to 4 feet.

Spieth is 10 under for the tournament through his first eight holes in Saturday's third round and is just one shot off the lead held by Graham DeLaet.

FORT WORTH, Texas -- Jeff Overton was disqualified Saturday after violating rule 14-3/10.3 for using an alignment device during his round.

"It's a shame but it's the rules," said Mark Russell, PGA TOUR vice president of rules and competition. "Not much we can do about it. ... We don't like to disqualify players but if that's what the rule says, we don't have a choice."

With the field backed up at the turn during the third round, Overton was waiting to tee off on the 10th hole. While he was waiting, Overton went over to the nearby practice green to practice a few putts.

Players are allowed to practice putting or chipping in those situations. But they cannot use any kind of artificial aid. Overton used a putting aid, which violates rule 14-3/10.3: Use of rod during round for alignment or as swing aid.

"You can go to a designated practice area and chip and putt if you'd like while you are waiting to play," Russell explained. "But you cannot use an artificial device. That's what he did. The penalty for that is disqualification."

Russell said another player noticed Overton using the practice aid on the green and asked a scoring official if that was legal. The official contacted rules officials, and John Mutch, a rules officlal with expertise in equipment-related rules, was consulted.

Mutch was the official who notifiied Overton of the disqualification after Overton struck his tee shot at the 11th hole, having just parred the 10th.

"Jeff's response? I don't think he was very happy," Russell said. "I certainly would expect that."

Overton said on his Twitter feed that he was informed by a rules official that he could chip and putt while he waited, but that he was not told to avoid using an alignment device.

"If ur gonna inform someone on a rule of something a person can do, make sure u remind them of the small things they can't do," he tweeted.

Overton had entered the third round 4 under for the tournament, just six strokes off the lead. He was still at 4 under when he was disqualified.

FORT WORTH, Texas -- Matt Kuchar has suffered just one bogey through his first 36 holes, one of the big reasons he finds himself leading the Crowne Plaza Invitational at Colonial at the halfway point.

He'd like nothing more than to continue staying out of trouble this weekend. Kuchar, at 10 under, tees off in Saturday's third round at 1:30 p.m. ET with a one-shot lead over playing partner Graham DeLaet.

"It's just steady golf," Kuichar said about the key to his success in his first two rounds. "Nothing special. Driving it well, putting it well, approaches are good. It's just been steady golf and I kepty myself out of trouble."

This is the sixth time in Kuchar's career that he has held or shared the 36-hole lead. The last time he did it was the THE PLAYERS Championship in 2012. He ended up winning the tournament, the biggest of the five wins in his PGA TOUR career.

"It's the best place to be, all right," Kuchar said about his position after completing his second round Saturday morning. "I think you always want to be in the lead with as big a lead as you can get.

"So the plan for the next 36 holes is to try to keep it going, try to make birdies."

If he goes on to victory, Kuchar will end a streak of 10 consecutive TOUR events in which the 36-hole leader/co-leader has failed to win. The last player to do so was Tiger Woods at the World Golf Championships-Cadillac Championship.

The system that dumped an enormous amount of rain in the Texas Hill Country could be headed to the Metroplex area.

Storms are forecast to arrive around 4 p.m. ET, or about halfway through the final group's third round at Colonial Country Club. Roughly half of the PGA TOUR events in 2013 have experienced some sort of weather delay, and Friday's second round spilled over into Saturday morning.

FORT WORTH, Texas -- Bill Rosinski from SiriusXM PGA TOUR Radio spoke with Steve Flesch, Freddie Jacobson, Josh Teater, and Jordan Spieth prior to their tee times in Saturday's third round of the Crowne Plaza Invitational at Colonial.

Prior to the third round of the 2013 Crowne Plaza Invitational at Colonial, Tom Werme and Fred Albers from SiriusXM PGA TOUR Radio describe the approaching storms and some players they are watching.

The field will use split tees for the third round at Colonial (full tee times here) after several groups had to come back Saturday to finish the second round.

Final two groups:

Matt Kuchar, Graham DeLaet, Josh Teater (1:30 p.m. ET): Kuchar has never won at Colonial, but he's never missed a cut here, either. Neither DeLaet or Teater have ever won on TOUR. DeLeat's 9 under total is his career low through 36 holes. Teater is 10 under on the back nine this week, marking the lowest back nine total through two rounds since 1983.

Jordan Spieth, Steve Flesch, Freddie Jacobson (1:19 p.m. ET): Spieth, a Dallas native, has all but locked up a PGA TOUR card in 2013-2014. A win at Colonial would lock up lot more than that. It would give him a spot in the FedExCup Playoffs, next year's Hyundai Tournament of Champions, and the Masters. Flesch, 46, has been the surprise of the tournament so far. He won this event in 2004, which earned him a spot in the field this week. This was his first made cut since 2011, and he's trying to become the 13th two-time winner at Colonial. Jacobson, like Kuchar, has just one bogey in 36 holes.

Martin Laird drained a 19-footer for par on the par-4 18th Saturday to become the last player to make the cut in the Crowne Plaza Invitational. The cut ended up at 1 under, and Laird birdied three of the final six holes to sneak in. A total of 78 players made the weekend.

Notables missing the weekend:

Charl Schwartzel (Even). The 2011 Masters champ made only five birdies.
David Hearn (2 over). The Canadian shot 64 on Thursday, then went sideways with a Friday 78.
Corey Pavin (Even). The 53-year-old former Colonial winner missed the cut after bogeying final hole.
Steven Fox (Even). Reigning U.S. Amateur champ nearly made first career TOUR cut.

Matt Kuchar will carry the 36-hole lead after finishing his second round with a couple of pars on Saturday at Colonial.

Kuchar was among those who had to return to Colonial to finish the second round after thunderstorms stopped play Friday afternoon at the Crowne Plaza Invitational. Kuchar opened with rounds of 65-65 at Colonial, with only a bogey on the difficult par-3 fourth in the opening round.

Surprisingly, Kuchar has never finished better than ninth at Colonial (2008) even though the veteran pencils in this stop on his schedule every year. 

Canadian Graham DeLaet is only a shot back and will likely play with Kuchar when tee times are announced later Saturday. On Friday, DeLaet had the distinction of playing the Horrible Horseshoe (holes Nos. 3, 4, 5 at Colonial) in 2 over.

Metroplex native and resident Jordan Spieth is only two back despite a strange penalty on Friday, and 2004 Colonial winner Steve Flesch was also just two back. It was Flesch's first made cut since the 2011 season. The 46-year-old lefthander has moonlighted this year as an analyst on the Golf Channel.
