"We withstood all that they had for tonight," Hollins said. "They just didn't shoot the ball well. They had a lot of open looks."
The Grizzlies scored the first nine points of the second quarter, opening a 32-22 lead, before Jennings made a running shot, got fouled and made the free throw.
Ellis also got off to a rough start, missing his first seven shots from the field. He finished the first half making only three of 12 shots from the field. He and Sanders were whistled for technical fouls in the second quarter. Jennings finished the first half with 13 points but made just four of 12 shots.
"We had a bad shooting night," Jennings said. "We missed a lot of layups, especially myself. They were layups that I usually make. We also gave up a lot of second-chance shots."
Bucks coach Scott Skiles wasn't pleased with his team's performance on either end of the court.
"Our defense wasn't good at all," he said. "Other than a few minutes early in the game and a few minutes in the third, they pretty much owned us in every area. We must have missed 15 layups. (Memphis) had all the energy, they had all the toughness, they executed better, so they took it to us."
