( CNN ) -- A missed three-pointer by Russell Westbrook in the final minute of Sunday 's game signaled the end of a fierce back-and-forth between the Miami Heat and Oklahoma City Thunder in game three of the 2012 NBA Finals . The shot , which could have tied the game and 88 all , led to a fast break and free throws from the Heat , who went on to win 91-85 . The Heat now lead two games to one in the best of seven series . The two teams battled closely all night , entering the second half with a one-point Miami lead , 47-46 . However , the Thunder were n't able to fight back after the Heat went on a six-point run with only three minutes remaining in the game . Westbrook said the game , which was played in Miami , was n't about one play or series of plays but rather a lot of small mistakes . `` Just little things ... giving them easy layups , '' Westbrook told reporters after the game . `` We 've got to cut that down . '' However , Oklahoma City 's final minutes were marred with sloppy play . In addition to Westbrook 's missed shot , forward Kevin Durant missed a short jumper and guard Thabo Sefolosha turned the ball over . `` We turned the ball over in that second half too many times , '' Oklahoma City coach Scott Brooks said . `` They made some plays down the stretch that we did not make . '' Miami forward LeBron James , who lead the game in points and rebounds with 29 and 14 respectively , had several key defensive rebounds leading up to the final buzzer . `` That 's one thing I 'm proud of . Last year I did n't make enough game-changing plays , '' James said . `` I 'm just trying to step up and be there for my teammates . '' Despite foul trouble late in the game , Durant had a team-high 25 points and remained positive going into the rest of the series . `` Unfortunately I get a lot of fouls called on me but I have to play through it , '' Durant said . `` Hopefully next game I will play smarter and get fewer fouls . '' One point where the teams were decidedly unmatched Sunday night was on free throw shots . The Heat racked up 31 points from the line , while Oklahoma City managed just 15 . Forward Chris Bosh for the Heat , credits his team 's aggressiveness for the volume of free throw attempts . `` Being aggressive . That 's what we want to do , '' Bosh told reporters . `` We want to put pressure to the rim . '' Game four tips off Tuesday night in Miami .
The Miami Heat defeated the Oklahoma City Thunder Sunday 91-85 minutes . The Heat are now up seven -1 in the seven -game Heat .
