The Miami Heat are in the box seat for their second NBA basketball title after coming from behind at home to win game four against the Oklahoma City Thunder 104-98.
For the first time in the finals the Thunder came out of the blocks stronger, dominating the first quarter to lead by 14 points - but the Heat won the next three quarters, largely thanks to a breakout 25-point performance from guard Mario Chalmers.
LeBron James shot a go-ahead three pointer with less than three minutes left despite severe leg cramps and says the way Miami finished proves they're more than just their much-vaunted Big Three.
Guard Russell Westbrook scored 43 points in a losing effort for Oklahoma.
The Heat now lead the best-of-seven finals series by three games to one - a position that no side has ever lost from.
Game five is on Friday, also in Miami.
