Several of his 3-point attempts in this one were uncontested.
"I think they were giving up my shot, and I made them pay for it," Calathes said.
But he also recognized the importance of not turning the ball over while trying to get the Grizzlies' offense running through the frontline tandem of Gasol and Randolph.
"I think that was the biggest stat of the night for me, not turning the ball over," Calathes said. "I came into the game telling myself, 'Don't make a crazy play. Don't try to go overboard.'"
Memphis struggled early but outscored the Bucks 46-32 in the paint and outrebounded Milwaukee 48-38. The Grizzlies also went 6 of 10 beyond the arc, their best percentage in a game this season.
The Bucks held a 13-point lead in the first half. Knight scored nine in the third, but Memphis began to make a push at the end of the period — even adding a point after it was over when officials reviewed a shot by Mike Miller and ruled it a 3. That left Milwaukee with a 69-67 lead entering the fourth.
Memphis finally erased the deficit early in the final quarter, opening with a 16-4 rally to build its first double-digit lead of the night.
Calathes sparked the burst with a trio of 3-pointers, the third one coming with 3:14 left for a 90-78 lead that Memphis never relinquished.
"It is hard to play 41 minutes," Grizzlies coach Dave Joerger said of Calathes. "He has the ball in his hands a lot. Wow, what a great performance."
