COLORADO SPRINGS, Colo. -- Although Antonio Vargas still thinks about the cut that nearly ended his Olympic dream, his unprotected head will be clear when he steps into the ring in Rio de Janeiro.Vargas grew up sparring and competing in protective headgear, so he had never been cut in a fight before his face split open in that bloody loss at the U.S. Olympic team trials seven months ago. The gifted flyweight from Florida had to fight his way back through the challengers bracket, surviving to earn a spot on the team.Cuts havent been a major concern in Olympic boxing since 1980, but they will be a constant danger in Rio, where the 250 male fighters will box without headgear for the first time since Moscow.Fighters have had three years to adjust to the change, and theyve adapted with the same tenacity that made them boxers in the first place.Im always going to do what I have to do, Vargas said. I dont think its really changed my style. Ill still have the same style going into the Olympics. I just have to be careful.The International Boxing Association (AIBA) made a highly visible alteration to its sport when it removed the headgear ahead of the 2013 world championships. Many fighters are excited for fans to see a sport that looks more like the pros, but the move is still criticized by other fighters and coaches who believe safety has been made secondary to appearance, particularly because of the high potential for cuts in a short, multi-fight tournament.I dont think it was a good idea, taking off the headgear, because were still amateur, U.S. light flyweight Nico Hernandez said. I got cut on both eyes before. I got stitches and stuff from head-butts. I just dont think its as safe for the amateur boxers. But I also like it, because you can have more peripheral vision and you dont get as hot. Ive had a lot of fights without now, so Im used to it.The bulky protective pads were placed on Olympic fighters heads in 1984 because organizers wanted to improve safety, and theyve been pulled off the fighters heading to Rio for ostensibly the same reason.In its lengthy quest to become a professional boxing promoter with control over the Olympics , AIBA went to great lengths to establish a scientific backing for its decision to drop headgear. The IOC also cited research to support the notion that the bulky head guards reduced the number of knockouts and stoppages, thereby reducing concussions.Their conclusions have been disputed by other scientists and fighters alike, but the benefits of removing headgear go beyond any concussion data in an inherently dangerous sport: Quite simply, the removal of headgear allows television audiences to see the fighters faces.Billy Walsh competed in headgear for his native Ireland at the 1988 Seoul Olympics before becoming one of the amateur sports foremost teachers. The new U.S. coach has adjusted his instructions under the new rules.Without the headgear, weve now got to be a bit more mobile, a bit more flexible, a bit more careful of heads, Walsh said. Weve got to be a bit more elusive. With headgear, we just locked up. Weve had to adapt some skills and techniques, but weve adapted similar stuff we would have been teaching when they had headgear. We all have to adapt.AIBAs changes are expected to continue after Rio, too. Womens boxing kept the headgear for its second Olympic tournament because AIBA says it doesnt have enough concussion data on women, but most female fighters expect AIBA to remove their headgear next year. The male boxers are still wearing tank tops in the ring in another holdover from the sports amateur days, but those are likely to be removed soon as well.Hernandez is among dozens of top Olympians who got experience without headgear by participating in World Series of Boxing, one of two professional leagues launched by AIBA. The WSB fighters have five-round fights that largely resemble pro bouts.Even fighters who dont agree with the science of the decision credit AIBA for attempting to improve their sports marketability, and the governing body has conducted a lengthy campaign to persuade boxers to fight without the in-close, head-butting style that could ruin the tournament.Most of the American fighters also plan to turn pro shortly after the Olympics, so the absence of headgear gives them a head start on the process.But all fighters in Rio will have to be careful with the knowledge that one cut could end their Olympics.With no headgear, at first I was nervous, and I didnt really want to do it, 18-year-old U.S. middleweight Charles Conwell said. But when I got in there, it was the same, basically. You just have to worry about cuts and head-butts. Im less worried now, because Ive got more experience with it. I know the dos and donts of not having headgear on. So Im going to adjust, because I know theres going to be some dirty things that are going to happen out there. Josh McCown Jersey .

Spieth won a PGA Tour event as a teenager -- and now hes joining all those stars at next weeks British Open. The 19-year-old outlasted David Hearn of Brantford, Ont., and Zach Johnson on the fifth hole of a playoff Sunday to win the John Deere Classic, becoming the youngest winner on the PGA Tour in 82 years. "Overall I was pretty proud of the way I played all day today heading into the playoff," said Hearn. "I gave myself some great chances and I know the next time I give myself chances like that, Ill make them." Spieth, a Dallas native who doesnt turn 20 for another two weeks, hit a short par putt to earn a spot in the field at Muirfield. He is the first teenager to win since Ralph Guldahl took the Santa Monica Open in 1931. "I didnt think it would happen this early," said Spieth, who turned pro in December after an All-American season as a freshman at the University of Texas. "I had a plan. I guess the plan got exceeded." Spieth started the day six shots behind third-round leader Daniel Summerhays. A bogey on the first hole left him seven back with 17 to play. But Spieth forced his way into the playoff with three straight birdies. The last came when he holed out of the bunker from 44 feet, delighting a crowd that had expected to see Johnson, the hometown favourite, defend his title. Spieth caught a break when that 44-footer took a pair of fortuitous bounces. But he also put himself in that position with a brilliant final round. "The shot on 18 was the luckiest shot I ever hit in my life," Spieth said. "The fact that it bounced right and hit the pin and dropped down to the cup, its just extremely fortunate." Spieth, Hearn and Johnson all made par on the first four playoff holes. Spieth simply made one more to stave off Johnson and Hearn on the fifth.dddddddddddd. "You can dwell on certain little things in any given round. Had I made another birdie in regulation, we wouldnt even have had a playoff," said Hearn. "You can always find a shot somewhere along the way." Hearn also had a shot at the win, which would have been his first on the PGA Tour, as well. But he missed a makeable putt on the fourth playoff hole. "Congrats to Jordan. Hes going to have an amazing career, obviously. Hes an incredible talent to come on Tour at his age and have as much success as quickly as he has. So hats off to him," Hearn said. Johnson seized control from Summerhays midway through the final round of regulation and looked to be on his way to another win at Deere Run. But Johnson simply couldnt get enough birdies to put the field away, and his uncharacteristic bogey on No. 18 set up a three-man playoff. All three players had their chances to make a winning shot before the final hole -- with Johnson narrowly missing from the back of the green on a shot that clipped the cup on the first playoff hole. Johnson hit the ground in disbelief. It would turn out to be the closest he would get to victory. "I had my chances on the back side in regulation. I mean, I hit some really good shots and just didnt make anything," Johnson said. Spieth, Hearn and Johnson all went right on their final tee shot. Spieth scrambled out of the rough, though, finding the back of the green to save par and win his first PGA event. Woods, Mickelson and McIlroy were all 20 when they picked up their first victories, but none of them could match Spieth, who is now the fourth-youngest winner in Tour history. "Just got so lucky. Thats what it is. But right now Im extremely pleased, and a little worried about only having short sleeves going to Scotland," Spieth said. ' ' '
