FORT WORTH, Texas - Dustin Johnson had played Colonial only once before, six years ago when he didnt even make it to the final round. In his return to Hogans Alley, Johnson took a one-stroke lead after the first round. Johnson shot a bogey-free 5-under 65 on Thursday, driving a lot of 3-irons off the tees into the fairways and hitting 16 of 18 greens in regulation. "Ive got to keep doing what Im doing," Johnson said. "Ive got a pretty good game plan for the golf course off the tee. So Im going to stick to that, just trying to keep getting birdie looks on every hole." His only birdie on the back nine was a 2-footer at the 177-yard 16th hole. That was enough to lead after his front-side 31 that included a 45-foot birdie putt on the difficult par-4 fifth hole. Hunter Mahan, playing in the group ahead of Johnson, led before a double-bogey 6 at the 433-yard 18th hole for a 66. He was tied for second with Harris English, Tim Wilkinson and Robert Streb. Jimmy Walker, a three-time winner this season, and 20-year-old Dallas native Jordan Spieth were in the group of 10 players at 67. Mahan started eagle-birdie and was already 6 under after a 3-foot birdie on the 178-yard eighth hole. He had two bogeys and two more birdies before his drive at the 18th hole into the right rough, with trees blocking a clear shot to the green. After punching the ball back into the fairway, his approach came settled on the edge of the fringe and he eventually two-putted from 7 feet. "You have to get over it," Mahan said about the disappointing 18th. "Its all about the drive there." Adam Scott, playing as the No. 1 player in the world for the first time, shot 71 after playing his first nine holes at 4-over 39. Scott had bogey-6 on the straight 631-yard 11th hole, his second of the day, when he hit twice from fairway bunkers. After a two-putt from 11 feet at the 433-yard 18th hole, Scott was bogey-free the rest of the way, with consecutive short birdies after making the turn. "I thought I actually hit plenty of good shots," Scott said. "All of a sudden, I had the momentum going the way I wanted and managed to hang on for the next few holes." The Australian said he felt the same as he did before this week when he overtook injured Tiger Woods for the top spot in the world ranking. "Theres not a big difference," Scott said. "Its always the first tee nerves of starting a tournament out, but I certainly didnt feel that much different." Johnsons 65 was the highest score to lead after the first round at Hogans Alley since another 65 in 2002. There were opening 62s in two of the previous three Colonials. When he first played at Colonial in 2008, Johnson made the initial cut. But after a 72 in the third round, he was among six more players trimmed to reduce the field to 73 for the final day. Walker, the FedEx Cup points leader, also played a bogey-free round with a tremendous par-saver at the 470-yard fifth hole after hitting his drive left into the rough under trees. With the ball on a hill several inches below his feet, he hit an off-balance shot to the left of the green. He then chipped up over the bunker, and the ball rolled to inside 4 feet of the cup. "I kind of had a shot, and I went for it, he said. "I had a big high cut over the trees, and didnt hit a very good shot, but it came up just short of the green, and made a great up and down there." Matt Kuchar, ranked No. 4 in the world and with a chance to move to the top with a victory, had birdies at Nos. 11 and 12 early in his round. He then had five bogeys before finally getting his only other birdie on his 16th hole, an 11-foot putt on the 437-yard seventh hole, in a 72. That matched his highest score in his 29 career rounds at Colonial, where he finished second last year. Rickie Fowler, who stars in a series of funny commercials for tournament sponsor Crowne Plaza, played with flu-like symptoms and had two triple bogeys in an 80, the worst score in the 123-player invitational field.

Bettors knew who they wanted, though, putting early money on Denver and making the Broncos a slight favourite to beat the Seattle Seahawks in most of this citys legal betting parlours. Denver was favoured by 1 point at several books in the early betting, while others had the Broncos as high as a 3-point pick. The move to the Broncos came after some books had initially made the Seahawks as much as a 2-point pick in the game. "Were just trying to figure out what the market will be and get a feel of where money will go," said Jay Kornegay, who runs the LVH sports book and initially had the Seahawks favoured. "At this point it doesnt take a lot to move the line." At the South Point sports book, Jimmy Vaccaro was on the phone talking about where he thought the line was going to go when a bettor came to the window and put $25,000 on the Broncos. That moved the game from pick em to the Broncos being favoured by 1 point, as the odds were adjusted to take in the bet. "Take your best shot," Vaccaro said. "Its an intriguing matchup with no clear cut favourite." Time was just running out in Seattles win over the San Francisco 49ers when the first odds for the Super Bowl were posted at most books. Bettors quickly reacted by putting most of the early money on the Broncos in an initial burstt of enthusiasm for a game so even that some think it will break the record of $98.dddddddddddd.9 million bet in Nevadas legal sports books last year. "Its incredible already, theyre lined up betting this game like it started a half hour from now," Vaccaro said. "If we dont do $100 million on this game Id be really puzzled." Kornegay said he made the Seahawks a 2-point favourite in his opening line because the Seahawks have a slightly higher power rating than the Broncos and a defence that might be the key in a game played outdoors in what could be cold temperatures. "With the game being in New York and the early forecast for below normal temperatures that favours a defensive team," he said. "It also favours a running team and thats certainly an advantage to the Seahawks." Bettors, though, liked Peyton Manning and his chances of winning another Super Bowl, and they didnt wait long to bet the Broncos. Sports books adjust the line to try to balance money on each team, and the LVH went from posting Seattle as a 2-point favourite to Denver being favoured by 1 point in less than an hour. Most big bettors -- the so-called "sharps" who can move a line all by themselves -- wait until much closer to the game before placing their bets. "Its all small stuff now," Vaccaro said. "The smart guys are not going to grab either side right now until they see how this shakes out." 23:41ET 19-01-14 ' ' '
