The Miami Heat turned to their supporting cast Wednesday in an 89-88 victory over a similar team of young players from the Washington Wizards at the Las Vegas Summer League.
Justin Robinson, at 5-8 the smallest player on the court, converted the winning layup with 11 seconds to play, with forward Lamond Murray Jr., the son of the former NBA player, then coming up with a block against former NBA forward Ike Diogu just before the final buzzer.
Playing their third game in as many days, the Heat played it cautious with their prime roster talent, with first-round pick Bam Adebayo and returning forward Okaro White given the game off.
The Heat also were without undrafted Virginia point guard London Perrantes, due to a sprained left foot, missing his second consecutive game.
The Heat next play Thursday at 6:30 p.m. against the Los Angeles Clippers, who received a bye in the tournament portion of the Las Vegas summer league. The Heat entered as the No. 12 seed in the tournament bracket that opened Wednesday, after going 2-1 in their preliminary-round games.
Robinson, an undrafted guard out of Monmouth, led the Heat with 19 points on 7-of-9 shooting in 20 minutes.
"Coach let me stay in and then just pretty much gave the ball in my hands and said, 'It's your keys, take the car to victory,' " Robinson said of a late exchange with Heat assistant coach Chris Quinn, who is coaching the team during summer league. "I had to stay sound defensively and continue to share the ball down the stretch."
Robinson said he wasn't about to allow the moment to overwhelm, with the Heat otherwise facing elimination from the tournament bracket.
"Just play as hard as you can," he said, "that always been how I found myself on the court during my whole life, just playing hard and scrapping. So, I mean, nothing really changes when I came down here."
Robinson wound up in a scoring duel with Marcus Keene, an undrafted 5-9 guard out of Youngstown State, who led the Wizards with 18 points.
"Me and Marc actually worked out together in Washington," Robinson said of his pre-draft sessions. "To get a chance to go up against him on this stage is very, very fun."
Among the Heat starters was A.J. Hammons, the second-year outside-shooting center acquired from the Dallas Mavericks in last week's trade of Josh McRoberts. He finished with nine points and five rebounds.
With team executives Pat Riley, Alonzo Mourning and several Heat players looking on, the Heat got 17 points off the bench from Murray and 10 points and nine rebounds from forward Zach Auguste.
Heat summer forward Trey McKinney-Jones was lost in the fourth quarter after a hard fall injured his left shoulder in an 84-84 tie with 1:38 to play, taken directly into the locker room. He left the arena in a sling, with eight points on 4-of-9 shooting.
The Wizards got 13 points from former University of Miami guard Sheldon McClellan, who now goes by Sheldon Mac. Undrafted University of Florida forward Devin Robinson played briefly for the Wizards and did not score.
The game was a rematch of the Heat's 91-87 victory Monday over the Wizards.
