World No 1 Jordan Spieth fired the worst first-round score of his professional career to fall 16 strokes off the pace at the Northern Trust Open. Spieth struggled to an eight-over 79 in scoring friendly conditions on Thursday, as Camilo Villegas fired a birdie-filled 63 to surge up the leaderboard and open up a three-stroke lead over the chasing pack.The world No 1 told reporters earlier in the week that Riviera Country Club was a course he was excited to return to, but he was noticeably off the pace on his way to recording his worst round since the 2014 Tour Championship. Spieth now faces a battle to avoid a first missed cut of 2016 after carding eight bogeys and one double-bogey in an error-strewn display, with the 22-year-old unable to think of an explanation for why his first round went so wrong. The world No 1s last missed cut came at the Deutsche Bank Championship I feel really confident about where my game is, and I had a great range session, Spieth told reporters. There was nothing pinpointed that was wrong.I just played really poorly from good positions off the tee and didnt strike the iron shots bad either. I just overdrew it when you cant be left and I overcut it when you cant be right. It was just bad timing.Having two-putted the first and tapped in the second, Spieth carded a three-putt bogey at the next and missed another par-save from less than six feet at the par-three sixth. Spieth spoke to a PGA Tour official after his ball ended being positioned near a sprinkler head at the ninth A solid 20-foot gain was quickly cancelled out by back-to-back blemishes to see Spieth reach the turn in 38, before the 22-year-old briefly halted the bogey run with a close-range birdie at the 10th.After missing an opportunity from 10-feet at the par-five 11th, Spieths round quickly unravelled with four bogeys in a five-hole stretch, starting when a short putt lipped out at the 12th. Although Spieth recovered from another wayward tee shot at the 17th to leave a kick-in par, the world No 1 closed a day to forget with an uncharacteristic three-putt double-bogey at the last from less than 15 feet.The Masters and U.S. Open winner later said he had struggled adapting to a Riviera layout that had run firm and fast earlier in the week before it was softened by overnight rain.I found it very difficult to trust the way the golf course is playing, the 22-year-old added. Ive never played the golf course soft.Ive always played where you have to kind of float it on to the front of the greens and let it bounce, and I just never trusted the adjustment.Watch the Northern Trust Open throughout the week on Sky Sports 4 - your home of golf.

NASHVILLE, Tenn. -- The Nashville Predators see forward Mike Fisher as the perfect fit as the seventh captain in franchise history, replacing Shea Weber who was traded to Montreal in July for P.K. Subban in a stunning move.General manager David Poile announced Thursday they have named Fisher as their new captain. Fisher, 36, is going into the final year on his current contract, but Poile made it clear that wont be an issue.He can play here as long as he wants, Poile said at a news conference. I dont view this as a one-year captaincy. Well take whatever we can get from Mike both on and off the ice.Fisher was a full alternate captain the past four seasons and the Predators nominee for the King Clancy Award four of the past five seasons for his leadership. He won the NHL Foundation Award in 2012 and helped Ottawa reach the Stanley Cup final in 2007.Fisher said being named the Predators captain ranks among the top highlights of his career.Its an honor to be given the captaincy of this team, of this city that I love being a part of, Fisher said.ddddddddddddHopefully, were going to top that this year with the Cup. Thats the plan.The 6-foot-1 center played his 1,000th career NHL game March 3, the 300th player in league history to reach that mark. He tied for the team lead with five goals during the playoffs last spring. He had a point in each of Nashvilles first five games against San Jose in the second round, and he also scored the game-winning goal in triple overtime of Game 4 against the Sharks.Fisher won a career-high 53.4 percent of his faceoffs last season.Poile said he and coach Peter Laviolette had been discussing candidates to become captain after the trade that sent Weber to Montreal for Subban. The general manager said Fisher met each of the criteria they wanted.Mike Fisher is a great ambassador for this franchise, Poile said.The Predators, who lost to San Jose in seven games, report for training camp Sept. 22.
