Said Scott: "We lost track of him. He worked his way underneath the defense a few times. They are a very good interior passing basketball team."
Lawson's driving layup with 1:48 left snapped an 89-all tie and after Cleveland couldn't convert on its next two possessions, Gallinari connected on his decisive 3-pointer.
"I'm always confident. I'm always ready to take those shots," Gallinari said. "I was wide open. Ty got the ball to me and it felt good leaving my hand. I thought it was going in as soon as I released it. It was an important shot and it was important that we got this win at home."
C.J. Miles, who missed Wednesday's win over Atlanta because of a back strain, hit a 3 for the final points of the second quarter to stretch the Cavaliers' halftime lead to 56-45. It was their biggest advantage at that point.
