Leif Shiras claims Milos Raonic is a real dangerman at the ATP World Tour Finals after not playing at his best, but still proving too strong for Dominic Thiem on Thursday night. Raonic defeated the young Austrian to join Novak Djokovic in the semi-finals of the season-ending finale in London. Six months half price Upgrade to Sky Sports to watch Man Utd v Arsenal on Saturday and get the first six months half price The duo faced a shoot-out for second place in the group behind the Serb, and the fourth seed edged a tight first set and then broke at the start of the second to win 7-6 (7-5) 6-3 and become the first Canadian to reach the semi-finals. I dont think he was at his best and I think thats a bit of a warning sign for everyone else that he can still get better, said Sky Sports tennis analyst Shiras.He was certainly good enough when it counted and that was the growing sign of a growing elite player that you play your best when the pressure is on and you can deliver. Raonic was delighted after defeating Thiem to go through to the semi-finals of the World Tour Finals I think what you see in him is not only growing talents, but more of an all-court game, comfortable in all parts and of course his growing belief. Hes four in the world and although he hadnt won a Masters event or a Grand Slam, these are the steps of progression that hes sort of leading up to.Being in the semi-finals here hes given himself a great chance to maybe pull one off here, its very much within his reach and he has the weapons to do it. Raonic says he drew inspiration from Pete Sampras serve when he joined Leif at the SkyPad There could be a rematch of the Wimbledon final and Australian Open semi-final between Raonic and Britains world No 1 Andy Murray in the last four, depending on how the other group plays out on Friday and Shiras says if it is Andy Murray, then he had better watch out.On an indoor hardcourt, I think the conditions suit Raonics game really well so Andy Murray will have to play well, said the former professional. Raonic books place in semis Milos Raonic beats Dominic Thiem at ATP World Tour Finals I think Raonic has a shot. Im not sure what the percentage would be with Andy and Novak in there - two of the games greats. His odds of winning the title are not as great as theirs but you can never discount a guy like Milos.

WASHINGTON -- John Tortorella stood in the middle of the ice and bellowed at the top of his lungs: Too slow! Were too slow. Move the puck and skate.Tortorella was imploring Team USA to practice the way he wants them to play at the World Cup of Hockey. The U.S. was built to be big, strong and physical in hopes of beating up a favorite like, say Canada. But to win the tournament, the Americans will need to mix speed, skill and scoring with the old-school Tortorella hockey principles of grinding it out and blocking shots.The teams identity is in-your-face aggressive, while NHL MVP Patrick Kane and talented winger Zach Parise and others will bring the flash and flair as the Americans attempt to avenge a disappointing finish at the 2014 Sochi Olympics.I think a big part of our team and our makeup is our willingness and our physicality, but we also have some skill, Tortorella said. Theres going to be some fast teams here and we do have speed. I think people have kind of got locked in because the way weve gone with our team, yeah, we have some grind to it, but we still have a very quick hockey club here and that has to play into it.Tortorella earned acclaim in 2004 when he coached the Tampa Bay Lightning to the Stanley Cup with the mantra of safe is death. In subsequent stops with the New York Rangers, Vancouver Canucks and now the Columbus Blue Jackets, the firebrand coach has tried to win by clogging up the middle and demanding players sacrifice their bodies to get in front of pucks.In a best-on-best tournament with star players, Tortorella still wants a buy-in, a commitment to team hockey. The U.S. goal is to be difficult to play against by dictating tempo up the ice and cashing in on the scoring ability of Kane, Pavelski, Max Pacioretty and captain Joe Pavelski.Pavelski believes playing on NHL-size ice in Toronto benefits the U.S., which could get lost on the outside of a wider international rink. It also makes speed imperative.You cant just play a gritty game, said Kane, the Hart Trophy winner with a league-best 1066 points last season.ddddddddddddWith the team in here, the players we have, we want to play a little bit more a physical brand and make it harder on teams to have the puck and when they dont have it, keep it from them and make it harder to get it back. We feel we have all those ingredients in here.U.S. general manager Dean Lombardi didnt want to make an all-star team, either. He wanted to recapture the magic of the 1996 World Cup champions, who beat Canada to win that tournament 20 years ago. He chose gritty players like Detroit Red Wings winger Justin Abdelkader at the expense of better scorers.Like legendary coach Herb Brooks said at the 1980 Olympics, the U.S. doesnt have enough talent to win on talent alone. But it has more than most NHL teams, which presents a challenge on how to handle a group of stars.Tortorella has to manage how much rope he gives those guys, said forward Brandon Dubinsky, who has played for him in New York and Columbus. Kaners not going to play (Tortorellas) type of crash-and-bang game, and he goes out and plays 100 points a year. Youve just got to let that guy play. ... Its just finding a balance but at the same time trying to have an identity as a whole of guys that are just going to go out there and grind away.Even if Jonathan Quick, who will start in goal in the opening game Saturday against Team Europe, is at his best, the Americans need to produce goals. Theyll look to Kane, Parise, Pavelski and Sochi shootout hero T.J Oshie for that but also muck and grind and try to dredge up offense.Theres a time and a place for all of that and establishing ourselves early in games of our physical presence and getting in on the forecheck and our territorial game, center David Backes said. Once we do that, you can let the skill take place when were in the zone and occupying for extended periods of time.---Follow Stephen Whyno on Twitter at http://www.twitter.com/SWhyno ' ' '
