In the absence of the injured Roger Federer -- last seen taking the mountain air in Switzerland -- Juan Martin Del Potro might just be the most adored man in tennis.Though after all the affection and euphoria that Del Potros comeback appearances have been generating across three continents of late, in Europe, South America and then North America, he is possibly about to reach the limit of his global appeal with a long weekend in Glasgow, the city of Andy Murrays birth.Think of the Davis Cup semifinal between Britain and Argentina, which begins on Friday at the Emirates Arena, as the ultimate test of Del Potros new gilded status. It has often been said that you can put Federer on any court in the world, even against a local in a Davis Cup rubber, and the crowd cant bring themselves to turn on him, and perhaps Delpo, as he is known, is now in that category.Consider the noise, emotion and craziness in New York when he defeated Steve Johnson in the second round of the US Open -- its not often that someone is treated so warmly when playing, and beating, an American in America. How will it play out when he faces a Scottish opponent in Scotland, before an audience which is a good two, three times more vocal than the spectators on Wimbledons Centre Court? Perhaps, like Federer, Del Potros appeal really will transcend the tribalism of the Davis Cup.Though lets not be so foolish as to imagine that Del Potro -- a former US Open champion, and the silver medallist at the Rio Olympics -- should be expecting a Glaswegian love-in. Or a repeat of what happened in New York during his US Open quarterfinal defeat to eventual champion Stan Wawrinka when the galleries gave him a standing ovation and sung Ole, ole, ole, Delpo, Delpo.Seven years after hitting through Federer to win the 2009 US Open title, Del Potro has had another summer of euphoria. Despite his modest position in the world rankings of No. 64 as he pulls himself up the standings again -- and thats a distinct improvement on his pre-US Open status when that was a triple-digit number -- Del Potro would currently be on the top line of any worldwide popularity chart.So above even Murray, the Wimbledon and Olympic champion, with the pair expected to play singles on Friday, in what will be a rematch of the gold-medal match in Rio. Del Potro hasnt played a singles rubber in the Davis Cup for four years, though that should hardly have a bearing on the indoor hard court in Scotland. Of far greater relevance is how he has been performing at such a high level of late, including tormenting Murray in Brazil.Its going to be interesting, I think. All of the British guys are playing well, and they are the favourites to win, but this is the Davis Cup so anything can happen, Del Potro has said.Del Potros re-emergence as a force at the top of the game -- after missing so many years to wrist operations, and coming so close to quitting -- is one reason for his surging popularity. Another is his emotional nature. There isnt a more open and emotional man in tennis; its been a rarity this summer to see him without pink eyes and his head buried in a towel.Recall his reaction at Wimbledon, at what was his first Grand Slam for more than two years, when he defeated Wawrinka in the second round -- as he put it, it was a victory that made him feel alive again. Listening to comments like that, no wonder the tennis public have fallen for him,and fallen hard.That connection between Del Potro and his global followers was only strengthened by his Olympic-standard hitting and Olympic-standard emoting and hugging in Brazil, with his first-round victory over Novak Djokovic possibly the most emotional contest of any sport at the Games with both winner and loser weeping as they left the court. More tears followed when he defeated Rafael Nadal in the semifinal and again after losing a four-setter to Murray. The Olympics brought some of the happiest times of his life, he has said.And the US Open wasnt bad either, with the singing and chanting during his match against Wawrinka moving him to tears. Beloved, people said, and that wasnt over-selling him.Del Potro has the power and danger in his arm to blast a hole in Murrays and Britains Davis Cup ambitions. And yet, for all that, Glasgow might still reveal a fondness for the man.Tom Rathman Super Bowl Jersey .

Kyle Juszczyk Super Bowl Jersey .Y. -- Jayna Hefford scored the winning goal Friday as Canada survived a scare with a 4-3 win over Sweden at the Four Nations womens hockey tournament.Ronnie OSullivan was in sublime form on Sunday evening to conquer Neil Robertson 9-5 and win a fourth Welsh Open title.The 40-year-old has been in dazzling form all week in Cardiff, but was struggling at the interval in this thrilling final, trailing the Australian 5-3.But the Rocket stormed back to take all six frames and he even ended the night with a stunning break of 141 to get his hands on a cheque worth £60,000. OSullivan, who also won in 2004, 2005 and 2014, said: I played a lot better here this week than I did at the Masters and really found some fluency.It is a fourth Welsh Open title - but Id like it better if I could win it five times. I feel shattered, and could really do with relaxing for a month, playing some exhibitions in order to give Sheffield and the world title a real shot. Thats the one we all want.I think Neil is the best player at the moment. He was at 75 or 80 per cent tonight but I was determined that if he won, he was going to have to earn it.Speaking after his semi-final win over Joe Perry, OSullivan seemed to be looking forward to facing his fierce baize rival by comparing Robertson to RoboCop.But Roobertson looked anything but robotic at the start of this contest with a smooth 78 and 76 helping him to a two-frame lead at 3-1.dddddddddddd Neil Robertson said: In a way I feel I threw it away. A knock of 77 had the Thunder from Down Under looking dominant at 5-2, but that was as good as it got.OSullivan may have started the tournament in controversial fashion by rejecting the chance to score a maximum 147 because he deemed the prize on offer to be too cheap, but when it mattered, he turned on the style.Robertson had his chances, but OSullivan eased through the gears and breezed over the line with breaks of 67, 70, 61 and 141 in the last four frames.It has been a remarkable show by a player of even OSullivans standards, having come back to win the Masters in December after a seven-month break. In 2016, the five-time world champion has won all 19 of his matches.His 28th world ranking title means he is level with Steve Davis and John Higgins. ' ' '
