Oklahoma City Thunder and the San Antonio Spurs record victories in Tuesday's NBA action.
The Miami Heat's home struggles continued on Tuesday, as the Oklahoma City Thunder won 94-86 at the American Airlines Arena.
Miami have battled at home this season, with the absence of star LeBron James - who moved back to the Cleveland Cavaliers - keenly felt.
And they slumped to a 7-13 record for the season in Miami as the Thunder proved too good.
The Heat made a bright start and led 27-24 at the first change, and they were still in front at the main break.
But Miami scored just 36 points in the second half as, for the final three quarters, they shot at just 42 per cent.
That gave the Thunder every chance and stars Russell Westbrook (19 points, 10 rebounds, six assists) and Kevin Durant (19 points, eight rebounds, eight assists) led them to victory.
Durant hit just nine of 24 field-goal attempts, while he was none from eight from long range.
But despite his unusually poor shooting, the Thunder - helped by a 16-point contribution from Reggie Jackson off the bench - proved too good.
Miami, who trailed by five points at the final change, had three shots to either tie or take the lead in the last quarter, but missed them all.
Dwyane Wade was Miami's best with 18 points and six assists. Chris Bosh also chipped in with 16.
The win saw Oklahoma's win-loss ratio move to positive, having won 21 of their 41 matches this season.
Miami, who have also played 41, have won just 18 - a far cry from past seasons.
Monday's other match saw defending champions San Antonio post a 109-99 win over the Denver Nuggets.
The two sides came into the clash in contrasting form - Spurs were going for a fourth straight win, while the Nuggets had to find a way to bounce back from being smashed 122-79 by the Golden State Warriors.
Denver stuck with the Spurs for the first three quarters, trailing 80-76 at three-quarter time.
San Antonio skipped away in the final quarter, though, as Kawhi Leonard stole the show with 17 points and 15 rebounds.
Tony Parker (18 points, seven assists) impressed too, while Australian Aron Baynes continued his good form off the bench with 15 points for the victors.
Kenneth Faried and Aaron Afflalo were Denver's best, with 26 and 21 points respectively.
