The 6-foot-8 Parker struggled against Arizona's physical interior defense and was 7 of 21 from the field. He came into the game shooting 60 percent from the floor.
Johnson, the tournament MVP, tied the score at 45 when he drilled a 3-pointer with 11:07 left in the game. That started a 16-6 run by the Wildcats that ended with 3:58 to play and Arizona comfortably ahead 61-51.
Johnson and Gordon scored five points apiece in the run.
"I was just trying to stay with it," Johnson said of his second-half performance. "I got into foul trouble early in the first half and it kind of got my rhythm a little down, but I just tried to stay with it.
"T.J. (McConnell) found me on a few plays and I just knocked down the shots."
"We're not going to win unless Jabari (Parker) and Rodney (Hood) shoot the ball. They (Arizona) have taller guys and if you do get the ball around the basket they're 6-9 or 6-10, that's a big front line.
"We don't practice against that. Two things you can't practice against is length and quickness. We have quickness, but not length."
"He (Gordon) stayed patient," Miller said, "which is one of the qualities that he has as player. I chose not to play him a lot in the first half because he was in foul trouble, but we as a group have to find more ways to use his offensive talent even more.
"He's such a unique player. You can put him in different positions and he can really excel. You would think that someone 6-8 would not be good in a ball-screen and pick-and-roll action, but he's very good in that."
