BALI, Indonesia -- Stephen Harper has dropped his prime ministerial gloves and put on his hockey historians helmet to wade in on the subject of violence in Canadas most popular sport. And he did so from a beach-front hotel in Bali, Indonesia, of all places. The prime minister, who has a book coming out next month on the early history of professional hockey, prefaced his unsolicited comments Tuesday on his role as an author, not as a politician. "Since Im taking off my hat soon on this (hockey historian) business anyway, as you know, I welcome the opportunity to comment on it," he told bemused reporters at a closing news conference following a summit of Asia-Pacific leaders. Harper -- a sharp-elbowed partisan in the political game -- said hockey is a rough sport but hes an admirer of skill over brawn. "I do think that authorities have historically not taken their responsibility to try and keep the rough, tough part of the game within the rules," he said, adding hes particularly concerned about head shots. "These are very serious issues and they do have to be taken seriously by the NHL and other sports bodies." Last weeks opening of the 2013-14 NHL season saw a nasty incident in which Montreal Canadiens enforcer George Parros pitched to the ice during a battle with Toronto Maple Leafs tough guy Colton Orr, falling hard on his chin and knocking himself unconscious. The Parros incident was one of several that marred the early season and renewed yet again the debate over fighting on ice. "Im not trying to be nonchalant about some of these incidents, which I think are of concern to any parent watching this and seeing examples set and worrying about what could happen to their own boys and girls when they step on the ice," Harper said, speaking in a hotel penthouse room overlooking the Indian Ocean. "That all said, what we all have to realize is that this debate is as old as the game itself." In fact, said historian Harper, "there has never been an era in hockey, including from the very beginning, where violence was not an issue of controversy." Matters are actually less rough today, said the prime minister, who called the level of violence in pre-war hockey "quite shocking." Harpers coming book is titled "A Great Game: The Forgotten Leafs and the Rise of Professional Hockey." Author and Globe and Mail columnist Roy MacGregor acted as an editorial consultant on the book, which is to be released Nov. 5, with proceeds going to a military charity. Josh Kline Jersey .

With his back to goal, Mbia backheeled Ivan Rakitics bouncing free kick over goalkeeper Victor Guaita for the opener after 33 minutes. Mbia appeared to score after receiving in an offside position. Guaita could do little moments later as Bacca raced free into the area to fire a low shot past the outstretched Valencia goalie to put the Andalucian club in command and on the verge of its first final since winning the second of consecutive UEFA Cups in 2007. Sevilla keeper Beto denied late Valencia substitute Jonas from point-blank in the 87th to preserve the advantage, then Eduardo Vargas headed off the crossbar as Valencia nearly scored a valuable away goal. "We played a good game against a great rival," Bacca said. "Despite the result, it wont be easy in the return." Valencia must rebound in one week at its Mestalla Stadium with a place in the May 14 final at Juventus Stadium in Turin at stake. Benfica won 2-1 at home to Juventus in the other semifinal. Valencia was fortunate to only be two goals down after the first leg after it failed to produce any concrete opportunities while relying on Guaita for important stops. Valencia doesnt have to look far back for inspiration after overturning a 3-0 first-leg deficit against Basel to reach the last four. "Im happy with the team and the effort they made," said Valencia coach Juan Antonio Pizzi, whose club is looking to return to its first final since winning in 2004.dddddddddddd "I dont think the result reflects the effort we made tonight." The visitors started brightly with Joao Perreira testing Beto with a swerving shot from outside the area, but the hosts took control after that through Rakitic. The Croatia midfielders free kick was headed on to the far post where Mbia, who appeared to be offside, got turned around trying to reach it as it bounced through his legs before recovering for the athletic score. Valencia looked demoralized right after Victor Perez combined with Bacca to play the Colombian through to create a two-goal cushion. "One of the most important things is that we didnt concede," Bacca said. "We could have had a third, but them too." Bacca was dangerous throughout, forcing Guaita to save his header and a solo effort set up by Rakitic in the 56th, either side of Guaitas save on Federico Fazios header. Sevilla midfielder Vicente Iborra headed over goal in stoppage time after Valencias final flurry of chances. "Were strong at home and we can come back from this," said Valencia forward Pablo Alcacer, who will miss the return after being booked for trying to avoid contact with Beto, who stuck his leg out at the Valencia midfielder in the closing moments. "Were going to try and get the yellow rescinded. Its clear I didnt do anything."
