Khris Middleton and Bobby Portis scored 29 points apiece and the injury-riddled Milwaukee Bucks stayed alive with a 115-92 victory over the visiting Indiana Pacers on Tuesday night in Game 5 of their Eastern Conference first-round playoff series.

Portis made 14 of 24 field-goal attempts and collected 10 rebounds. Middleton had 12 rebounds and five assists as Milwaukee cut its deficit to 3-2 in the best-of-seven series.

The Bucks controlled the contest despite both Giannis Antetokounmpo (calf) and Damian Lillard (Achilles) sitting out. Antetokounmpo has missed the entire series and Lillard has sat out the past two games.

"I told our coaches we were coming to play and win tonight," Milwaukee coach Doc Rivers said after the game. "That was not a team walking through the walkthrough thinking this was it. That was a team thinking it could win, and it showed."

Tyrese Haliburton scored 16 points and Myles Turner added 13 for Indiana. Pascal Siakam, Andrew Nembhard and Obi Toppin had 12 apiece.

Game 6 is Thursday night in Indianapolis.

"I think we have to understand they're a team on the brink of their season being done. They're playing desperate, they're playing hard," Haliburton said. "At the end of the day, they just outcompeted us (Tuesday), they played harder, they were better and they dominated us in every facet of the game. We have to be better, top to bottom."

Malik Beasley scored 18 points and joined Middleton in making four 3-pointers. Patrick Beverley recorded 13 points and 12 assists, and Brook Lopez had 12 points for the Bucks.
