MIAMI -- Here they are again, back on the brink of a championship. It slipped away from the San Antonio Spurs last year, but it would take something special -- historic, actually -- to stop them now. The Miami Heat would have to make the biggest comeback in NBA Finals history. "Theyre the two-time champs, theyre a great team, and there is still one more game," Spurs guard Tony Parker said. "We have to win one more game." Kawhi Leonard had 20 points and 14 rebounds, and the Spurs routed the Heat again, winning 107-86 on Thursday night to open a commanding 3-1 lead. The Spurs can win their fifth NBA championship with a victory at home in Game 5 on Sunday and avenge their seven-game loss to Miami last year. They have three chances, and the way theyre dominating the Heat, they might need just one. "Im pleased that they performed as well as they did while weve been in Miami, and thats about as far as it goes," Spurs coach Gregg Popovich said. "Now weve got to go back home and play as well or better." LeBron James had 28 points and eight rebounds, but Dwyane Wade was just 1 of 10 through three quarters and finished with 10 points. "They smashed us," James said. "Two straight home games got off to awful starts. They came in and were much better than us in these last two games. Its just that simple." No team has overcome a 3-1 deficit in the finals, and the way the Heat were outclassed twice on their home floor makes it hard to imagine the two-time champions being the first. "We put ourselves in a position where it is about making history," James added. Parker added 19 points, and Tim Duncan had 10 points and 11 rebounds for the Spurs, who shot 57 per cent from the field and are hitting 54 per cent in the series. The Spurs lost twice in Miami to end last years finals, their only defeat in the championship round. They won their two games in South Florida this time by a combined 40 points. San Antonios surprising dominance has Miami on its heels, and unless Miami can figure things out quickly, the Heats two-year championship reign will come to an abrupt end. If this was the last home game of the season in Miami, it looked and sounded nothing like the ones to end the last two years, which featured confetti falling and trophies raised. This one had the unfamiliar sound of boos late in the first half and a chant of "Go Spurs Go!" with under 3 minutes left from the San Antonio fans who remained long after many of Miamis had bolted. A Heat win Sunday would force a Game 6 in Miami Tuesday. The Heat had followed their last 13 post-season losses with a victory, but now at the end of a fourth straight season that has gone the distance, they might be out of gas. Miami seemed to lack the energy -- or maybe effort -- to defend San Antonios precision ball movement for the full 24 seconds, and time after time the Spurs ended up with a shot from somebody who didnt have a defender nearby. Not quite as sharp as when they shot a finals-record 75.8 per cent in the first half Tuesday night, the Spurs were still plenty good enough to open another huge lead by halftime, and they withstood every attempt Miami made to make a run. "We were expecting a reaction from them but we were ready for it, so we just did the same thing," Spurs forward Boris Diaw said. The Spurs knew their defence had to be better, realizing their once-in-a-lifetime, 19-for-21 start in Tuesdays 111-92 Game 3 victory covered the fact that they allowed Miami to make more than 50 per cent in the game. They held Miami to 35 per cent in the first half. "They played great and I can honestly say I dont think any of us were expecting this type of performance," Heat coach Erik Spoelstra said. San Antonio blew the game open late in the second quarter with seven straight points, capped by Leonards soaring follow dunk that made it 55-33. James, who battled cramps in Game 1, left the court and briefly returned to the locker room midway through the first quarter Thursday. But he had 10 quick points in the third quarter to bring Miami within 13, but San Antonio pushed it to 81-57 after three and never looked back. Notes: Under Popovich, the Spurs have won 15 of the 18 best-of-seven series in which they led 2-1. ... The Heat hadnt lost back-to-back games in the playoffs since dropping three straight against the Boston Celtics in the 2012 Eastern Conference finals.

Neither striker Demba Ba nor Fernando Torres came close to scoring as Chelsea was left unsuccessfully appealing for penalties in this drab penultimate game of the season. "Our strikers are good strikers, no doubt about that, but players with some specific qualities," Mourinho said. "They are not the kind of players in five square meters with three or four players around who can get the ball, can dribble around and make the shot. "So when the team is in a difficult situation they are not able to normally resolve that situation for us." It likely means Mourinhos first season back at Chelsea will end without a trophy. Chelsea, with one game left, is a point behind Manchester City and Liverpool, who both have two matches remaining and a superior goal difference. "We tried everything but at the end of the day we knew we had no chance of being champions," he added. Chelsea is three points ahead of fourth-placed Arsenal, which also has one game left, but the Blues have a much better goal difference. A draw at Stamford Bridge would usually be something to celebrate for Norwich -- giving Neil Adams his first point in his fourth game as interim manager -- but it leaves the club closer to the drop. Norwich needs Sunderland to lose to West Bromwich Albion on Wednesday and Swansea on Sunday, when the Canaries must beat Arsenal. Realistically, the season seems to be over for both Norwich and Chelsea, which still seemed to be affected by Wednesdays Champions League semifinal loss to Atletico Madrid. "The first half was typical of the consequence of that state of mind," Mourinho said. "It was a lazy first half," he added. "Slow, no pressure, the midfield werent arriving to press the opponent." Chelsea was forttunate that referee Neil Swarbrick dismissed Norwichs penalty claims after 11 minutes when Martin Olsson was fouled in the area by John Terry.dddddddddddd Chelsea didnt make the most of its reprieve, with the hosts unable to trouble goalkeeper John Ruddy, who easily saved Terrys header. Andre Schuerrle did manage to hit the inside of the post but his follow-up was easily collected by Ruddy, and Willian completely miscued a shot just before half time. Defender David Luiz made a quick impact at the start of the second half after replacing Frank Lampard, but the crossbar denied Chelsea this time. Then came Chelseas penalty claims, with Schuerrle first brought down by Alexander Tettey and Ryan Bennett making slight contact with second-half substitute Eden Hazard. "Hazard, I saw," Mourinho said. "I saw in the game, but to confirm I had a quick run to my office which is just there, and I arrived in time to watch and then go back to the dug-out laughing ... because I cant cry." With one of his assistants, Rui Faria, starting a six-game stadium ban for misconduct toward match officials, Mourinho imposed a vow of silence toward Sundays referee. "My assistant is in jail and I dont want to comment," Mourinho said. The Portuguese was happier discussing another unsatisfactory performance from his strikers, summed up by Torres failing to make a clean connection late on after Hazards shot was parried. For Mourinho, the summer mission is to overhaul his strike force with Atletico striker Diego Costa primed for a move to west London. "Its a long summer for us ... to sit and to discuss and analyze options, the market," Mourinho said. Veteran players could be leaving, with 33-year-old defender Ashley Cole out of contract at the end of the season and tearful on the pitch after Chelseas final home game. Terry, who embraced the emotional Cole, and Lampard are also yet to secure new contracts. "They are with the club on their future," said Mourinho, who wants the trio to stay. ' ' '
