The Pac-12 tournament championship game between Arizona and USC tips at 10 p.m. ET on Saturday. The Wildcats opened as 1.5-point favorites, while the Over-Under, or total number of points Vegas thinks will be scored, is 146.

Before making any kind of pick on this matchup that is virtually dead even, you need to see what SportsLine's advanced computer model has to say.

Last season, the model was an impressive 755-636-20 on A-rated picks, returning $6,529 to any $100 player who followed it. And with the NCAA Tournament just around the corner, the model is heating up, entering the Pac-12 final on a stellar 7-1 run on its top-rated college basketball picks.

Now, it has simulated USC vs. Arizona 10,000 times and its picks and projections are in.

We can tell you the model is digging the Under, saying it hits in 54 percent of simulations. In fact, it's calling for 144 total points to be scored, which would clear the Under by two.

And the model says one side is winning against the spread over 50 percent of the time. You can get that pick only at SportsLine.

The model knows Arizona beat USC by 14 earlier this season, but that game was on Arizona's home floor. Sophomore guard Rawle Alkins led the way for the Wildcats with a game-high 20 points and a team-high five assists. He was one of four Arizona players in double-figures.

But just because Arizona already defeated USC this season doesn't mean lightning strikes twice on Saturday.

USC is playing its best basketball of the season right now and won six of its past seven games. The Trojans haven't been squeaking by their opponents, either; all but one win over that stretch was by double-figures.

USC dismantled Oregon, a 22-win team, by 20 points on Friday, using a ferocious defense to hold the Ducks to just 33 percent from the field. USC won the rebounding battle handedly, 41-25.

So which side of Arizona-USC do you need to be all over? Visit SportsLine now to see the point-spread pick that hits over 50 percent of the time, all from the model that has crushed its college basketball picks.
