With an extra $1 million in his pocket, Kelly Olynyk could have afforded a spending spree.

"Instead, I just made it rain," he said.

One 3-pointer at a time.

Olynyk scored 19 points, including 15 on five 3-pointers when Miami took the lead for good in the second period, and the Heat beat the Atlanta Hawks 115-86 on Wednesday night, capping a sweep of back-to-back games between Southeast Division rivals.

By logging his first two minutes in the game, Olynyk earned a $1 million bonus for reaching 1,700 for the season.

That sort of detail doesn't go unnoticed on a team. Olynyk's teammates and coach Erik Spoelstra are expecting the 7-foot forward to pick up some tabs.

"Dinner, drinks, beers all that is on him," Spoelstra said. "I'm going to see if I can get tickets to a play. All that is on him. I'm going to bill his account for everything."

Spoelstra and his players have reason to celebrate.

Miami rested Dwyane Wade, Goran Dragic and James Johnson one day after clinching a playoff berth by beating the Hawks in Miami.

Olynyk made five of six 3s in the second period. His career high for 3s in a game is six.

"I was kind of in the zone," he said. "I felt like whatever I threw up was going to go in."

Olynyk's first two 3s in his streak of four straight for the Heat capped a 14-0 run for a 42-36 lead.

Following a basket by Atlanta's Damion Lee, Olynyk sank two more 3s before a miss ended his hot stretch.

"He's one of our best shooters," said Spoelstra of Olynyk. "He works on it all the time and it's such a weapon. And he picks the right spots. It's all because his heart's in the right place. He doesn't want to take all the shots. He only wants to shoot open ones."

Olynyk also had eight rebounds and five assists.

Josh Richardson also had 19 points, with four blocks and three steals, and Justise Winslow had 18 for Miami.

Miami stretched its lead with a 12-0 run late in the third quarter and increased the advantage to 20 points early in the final period.

Even without some of its top players, Miami had plenty of depth to control the game. The woeful Hawks have lost seven of eight and 13 of 15 to solidify their hold on the worst record in the Eastern Conference.

"Energy wise, our gas tank hit empty," said Hawks coach Mike Budenholzer.

Taurean Prince led Atlanta with 20 points, Lee and Tyler Dorsey each had 15. No other Hawks player scored in double figures.

"It's just one of those nights when we dug ourselves a hole," Dorsey said.
