Fredrik Jacobson has his first win in 188 starts on the PGA Tour. His two-putt for par on 18 gave him a one-stroke win over John Rollins and Ryan Moore.

Jacobson shot a 4-under-par 66 today, surviving the 63s that Rollins and Moore posted. Moore had a 4-foot putt for par on 18, but he missed and made bogey.

Michael Thompson was fourth at 18-under after shooting 62.

Jacobson made only one bogey all week, the 10th hole today, but he birdied 12 and 14 to get to 20-under. Moore tied him with a birdie on 16.

Jacobson, from Gothenburg, Sweden, has three wins in Europe. He was playing the Travelers for the fourth time: He tied for 48th in 2006 but missed the cut in 2007 and 2009.

John Rollins birdied the 18th to move to 19-under, leader in the clubhouse. Ryan Moore went from fairway bunker to greenside bunker and will need to work to stay at 20-under. Frederik Jacobson got up-and-down at 17 to save par and stay at 20.

Before that Jacobson putt, a three-way playoff didn’t look crazy. Less so now.

Edit: Moore made a nice shot out of the trap, leaving himself something like a 3-foot par putt. Jacobson’s in the fairway after a good bounce off a hillside.

Edit2: Moore missed the putt but made the bogey, so he’s in at 19-under after shooting 63 today.

After Frederik Jacobson parred 15, staying at 20-under, Ryan Moore birdied 16 to join him there. John Rollins is two back on 17. Michael Thompson has the clubhouse lead, at 18-under as well.

Frederik Jacobson made the turn with a two-shot lead over Ryan Moore and Michael Thompson, but he’s in some trouble on 10, which could create his first bogey of the tournament. Jacobson is at 19-under, with Moore (on 12) and Thompson (on 18) at 17-under.

Thompson is back at this tournament for the first time since he played here in 2008 as an amateur.

Fairfield’s J.J. Henry, meanwhile, has never put a run together and sits 1-under for the day through 14. He’s eight back.

Ryan Moore left himself three short birdie putts on the first three holes, made them all, and is 15-under-par, one shot off Frederik Jacobson’s lead. Edit: While I waited for that to post, Jacobson birdied No. 2, so he has a two-shot lead.

Veteran David Toms is the leader in the clubhouse at 12-under. He had 10 birdies in the first three rounds, then dropped in six today.

The leaders won’t be off the tee for another hour or so, but only one golfer has posted a really low score early, Steve Flesch. He had five birdies and an eagle on 15 to shoot a 7-under 63.

Of course, that only moved him to 11-under for the tournament. That’s tied for 10th right now. Unless the course suddenly plays a lot tougher, he’ll finish somewhat lower.

Patrick Cantlay has done things over the past week that many people would pay to do. Today, he did things that earn most people huge paychecks.

He won’t get paid, but man, what a day.

Cantlay, the amateur who just finished his freshman season at UCLA, tore apart TPC at River Highlands, setting the course record with a 10-under-par 60 in his second round of the day. Just 19 years old, he leads the tournament by four strokes.

Cantlay was the NCAA’s player of the year, and he earned his way into last week’s U.S. Open, where he tied for 21st as the low amateur. He got a sponsor’s exemption into this tournament. After a 67 this morning — forced to play 36 holes today because of yesterday’s rain — he rolled through the second round, taking the lead with an eagle on the 13th hole.

Four players had shot 61 at TPC River Highlands, most recently Brad Faxon in the final round of his 2005 tournament victory. Cantlay’s 60 ties the tournament record, which Tommy Bolt set in 1954 at Wethersfield Country Club.

A wild moment about a half-hour before Cantlay finished: The PGA Tour’s leaderboard suddenly showed Michael Thompson at 11-under, tied with Cantlay at the time. Somehow, the computer gave Thompson credit for a hole-in-one on the par-4, 443-yard seventh hole. That was promptly corrected. Coincidentally, Thompson was the last amateur to make the cut in this tournament, in 2008. Cantlay is now the fourth since 1979 to make it.

UCLA rising sophomore Patrick Cantlay has a share of the lead as he makes the turn in the second round of the Travelers Championship. Five birdies on the front nine, including one at No. 9, has the amateur at 8-under for the tournament (that is, today’s first 27 for him), tied with Vaughn Taylor.

Here’s the story I did on Cantlay earlier this week. Funny: He said he was tired, even yawning as he sat down for his press conference. Today, after he signed for his 67, he was about to go on TV… and he yawned again. Nothing fazing this kid.

The top of the leaderboard remains packed. A birdie here or a bogey there could make a world of difference for anybody.
