The San Antonio Spurs connected on an NBA Finals-record 16 3-point shots en route to a 113-77 rout of the Miami Heat in Game 3, although a hamstring injury to star point guard Tony Parker put a damper on their celebration.

Unheralded role players Danny Green and Gary Neal were the story of Tuesday night's victory at the AT&T Center in San Antonio, combining for 51 points and 13 3-pointers as the Spurs dominated the Heat in all facets of the game to take a 2-1 series lead.

The Spurs had a narrow 50-44 advantage at halftime, but their second-half three-point barrage blew the game wide open and both benches were emptied with several minutes left in the fourth quarter.

Green notched 27 points by shooting 9-of-15 from the field and 7-of-9 from three-point range.

Neal, for his part, was a major contributor off the bench, scoring 24 points on 6-of-10 shooting from behind the 3-point line, hauling down four rebounds and dishing out three assists.

Forwards Kawhi Leonard and Tim Duncan, meanwhile, each tallied a double-double in the easy victory.

The Spurs also comfortably won the rebounding battle by a margin of 52-36, exploiting a problem area for the athletic but undersized Miami team.

But a potential serious injury to Parker, the Spurs' top player all season and the MVP of the 2007 NBA Finals, would be a major blow to San Antonio's bid for a fifth title.

Although he played 27 minutes and had a game-high eight assists, Parker felt renewed discomfort in his right hamstring and will undergo an MRI on Wednesday to determine the extent of the injury, which has bothered him for several months.

Dwyane Wade led the way for the Heat with 16 points and five assists, while LeBron James - who was never comfortable with the Spurs' defensive schemes - had a second straight sub-par outing.

The four-time NBA MVP scored just 15 points on an uncharacteristically inefficient 7-of-21 from the field and did not make a single trip to the free-throw line. He did lead the Heat in rebounding, however, with 11 boards.

Heat power forward Chris Bosh had another mediocre scoring night with 12 points and is averaging just 12.3 points per game in the NBA Finals, well below his season average of 16.6 ppg.

Miami reserve Mike Miller kept the game close in the first half with hot 3-point shooting, but he was mostly a non-factor in the final two quarters, as were most of his teammates.

Game 4 on Thursday and Game 5 on Sunday also will be played in San Antonio.

The Heat will need to win one of those contests to force a Game 6 back in Miami next Tuesday. EFE
