Fredrik Jacobson is your 36-hole leader at the World Golf Championships-HSBC Champions. The Swede tied the event’s two-round scoring record, posting an 11-under 133 mark after Friday’s 6-under 66 at Sheshan International Golf Club. Louis Oosthuizen (63) and Adam Scott (65) gained ground on Jacobson, and enter the weekend just one shot off the pace. They will be grouped with Jacobson Saturday, teeing off at 10:40 p.m. ET. First-round leader Keegan Bradley had two bogeys, two birdies and an eagle Friday and enters the weekend two back. Bo Van Pelt, who won last week’s CIMB Asia Pacific Classic, and Paul Casey are each 8 under, three behind Jacobson. Defending Champion Francesco Molinari carded his second-consecutive 2-under 70 and is tied for 22nd, seven shots off the pace. Click here to read more about Round 2

Fredrik Jacobson won his first career PGA TOUR event in June at the Travelers Championship. He got his first top-10 since that victory last week in Malaysia and now could be the 36-hole leader at the World Golf Championships-HSBC Champions. Jacobson birdied two of his last three holes Friday to shoot a 6-under 66. At 11 under, he's in the clubhouse with a two-shot lead over Keegan Bradley (who still has five holes to play). Check out the video below to see Jacobson's 18-foot birdie putt on No. 9 (his final hole of the day).

Sweden's Fredrik Jacobson appears to have lost his clubhead during the third round of the CIMB Asia Pacific Classic. What is going on? Leave your answer below, and please, keep it clean! To see the best photos from last week, click here .

Jeff Overton broke the course record with a 9-under 62 Friday and joins Fredrik Jacobson atop the leaderboard at the midway point of the CIMB Asia Pacific Classic. Overton, who didn’t learn he was in the field until Sunday night, arrived in Malaysia early Wednesday morning but didn’t have his clubs at his disposal until Wednesday night. A new set of Cleveland irons helped him to open with three consecutive birdies in a round that also featured an eagle on the drivable par-4 15th en route to a share of the 36-hole lead. “I picked up a lot of feel,” Overton said. “I put them in play three or four weeks ago, about when I finished sixth at the McGladrey (Classic). I’m hitting them so good and have so much more confidence right now.” Jacobson started his Friday with a bogey but had five birdies in a six-hole stretch on the back nine to catch Overton at 13 under. “I feel like I’ve had a lot of short opportunities,” Jacobson said. “I’ve let some of them go and then I’ve made some long ones. It’s been a little bit of a tradeoff so far in the week. Maybe the ones I’ve thought I should knock in, I’ve had a hard time. But I made some other ones, so it’s been good.” Chasing the co-leaders is Bo Van Pelt, who is one shot off the pace at 12 under. Mark Wilson, Stewart Cink, Jimmy Walker and Jhonattan Vegas are four back at 9 under. Robert Allenby, who tied the old course record with a 63 in Round 1, was 1 over Friday and is tied for 9th, six back. CLICK HERE TO READ THE REST OF THE SECOND-ROUND WRAP-UP

A day after Robert Allenby posted an 8-under 63 to tie the course record, Jeff Overton one-upped him with a record-breaking 62 that has him tied atop the leaderboard after 36 holes of the CIMB Asia Pacific Classic. Overton and Fredrik Jacobson are each at 13 under following two days of play at The Mines Resort. Bo Van Pelt is alone in third, one shot back, while Mark Wilson, Stewart Cink, Jimmy Walker and Jhonattan Vegas head to the weekend at 9 under.

LEMONT, Ill. -- Math was Fredrik Jacobson's favorite subject in school.

But Jacobson sure didn't like the numbers he was seeing on the leaderboard after he made a quadruple bogey on the fifth hole Sunday. Not only was he 7 over for the tournament, the veteran from Sweden had tumbled outside the top 30 in the FedExCup after starting the BMW Championship ranked 23rd.

Jacobson pulled himself together, though, and played his final 13 holes in 4 under to shoot 72. He was 28th in the FedExCup when he finished and regardless of what happened as the day wore on, Jacobson was happy with the way he battled back.

"I saw I was 33rd or something (when he made the quadruple bogey)," Jacobson said. "At that point. I did know I was outside. I had to pull myself together and play some golf. I mean, it's still up in the air but at least I gave myself a shot at it now and that feels a whole lot better rather than being out of it completely..”

The mathematician in Jacobson knew he probably was too focused on all the permutations and projections early in the week. He acknowledged that "I wasn't too much fun being around" after he shot a 73 on Friday that moved him to 3 over for the tournament. A double bogey in his final two holes each of the first two rounds didn't help, either.

"(Math) was the one subject I was really good at so for me I've got to try and stay out of that stuff," Jacobson said. "When I get into that it's tough to focus on something else. I managed to put that aside much better on the weekend than earlier in the week. Early in the week I was a little short-fused and forcing the issue a little bit where I was a little bit more casual on the weekend and enjoyed myself a bit more."

"... I was happy with the way I handled things today."

Jacobson planned to grab lunch, probably push his flight back and hover near a computer until he was sure he was safe for his first trip to the TOUR Championship by Coca-Cola. He wished he had taken care of business earlier but he was proud of the way he rebounded from the disaster at No. 5 and gave himself a shot.

"We said all weekend to try to stay aggressive and try to play that way," Jacobson said. "Coming into the week I was thinking quite a bit about the standings and all that and all through the week. Little disappointed before the week that it wasn't a done deal. Still got to go out, and sometimes it's almost easier when you're got to finish top 15 or top 10 and play really well to get in than to maybe finish in the middle.

"It's a tough thing when you get caught up in that stuff to really play your game and to focus on each shot. It was a bit of a struggle earlier in the week. But I think thanks to getting a better attitude in the weekend, I dealt with that high number a lot better than I would have earlier in the week."

It didn’t take long for someone to catch Adam Scott -- Jason Day birdied the first hole and is now tied for the lead at 12 under.

But Day wasn’t the only one to get off to a fast start with Fredrik Jacobson, Rickie Fowler and Luke Donald all posting early birdies.

Now it will be Scott’s turn to see if he can answer. The only lead in a World Golf Championships event ever had coming into this week was after the first round of the Bridgestone Invitational in 2006 (he went on to finish in a tie for 10th). Prior to this week he’d also never led or shared the lead after all three rounds and gone on to win.

The good news for Scott, however, is that he has won five times in his career after holding the 54-hole lead, most recently at the 2008 EDS Byron Nelson Championship.

Scott is currently 50th in the FedExCup standings. A win would move him to No. 16 and almost guaranteed a spot in the season ending TOUR Championship by Coca-Cola. He won at East Lake in 2006, the year before the FedExCup began, but has only qualified for the PGA TOUR Playoffs finale twice in the past four years.

CROMWELL, Conn. -- Not only did Fredrik Jacobson record his first career victory in 188 starts on the PGA TOUR, he also earned 500 FedExCup points and moves from 41st to 18th in the standings.

During the first four years of the FedExCup, he has finished 84 ^th (2007), 44 ^th (2008), 57 ^th (2009) and 58 ^th (2010).

Jacobson’s 72-hole total of 20-under 260 is also the lowest winning score on TOUR this season, besting the 264 set by Sony Open in Hawaii winner Mark Wilson.

Jacobson, a 36-year-old native of Gothenburg, Sweden, becomes the first international winner of the Travelers Championship since Greg Norman in 1995. He is the seventh Swedish-born player to win on the PGA TOUR, joining Jesper Parnevik, Daniel Chopra, Gabriel Hjertstedt, Carl Pettersson, Richard S. Johnson and Henrik Stenson.

Jacobson played the first 63 holes this week without a bogey, with his only one of the week coming on the par-4 10 ^th hole when he missed a putt just under 12 feet for par. He was seeking to become the first winner since Lee Trevino at the 1974 Greater New Orleans Open to go bogey-free over 72 holes.

Lastly, Jacobson led the field this week in strokes gained-putting. He picked up 2.246 strokes per round over the field.
