The Miami Heat scored 70 points in the first half on the way to a 114-96 drubbing of the Indiana Pacers to take a 2-1 lead in the NBA Eastern Conference finals.

After splitting the first two games in Miami, the defending champion Heat arrived in Indianapolis with something to prove.

The Pacers, regarded as one of the NBA's best teams on defense, seemed powerless to contain the visitors, who were led by LeBron James with 22 points and Dwyane Wade with 18 points and a team-high eight assists.

Udonis Haslem had 17 points and the other member of Miami's Big Three, Chris Bosh, scored 15.

Game four in the best-of-seven series is set for Tuesday night at Bankers Life Fieldhouse in Indianapolis.

The San Antonio Spurs, trying to get back to the NBA finals for the first time since their 2007 championship run, needed overtime to pull out a 104-93 win over the Grizzlies in Memphis.

The victory gave the Spurs a 3-0 lead, putting them in a position to close out the series Monday night in Memphis.

Tony Parker had 26 points for San Antonio, followed by Tim Duncan with 24 - including 7 points in the overtime - and Manu Ginobili, who put up 19 points. EFE
