Jamaal Franklin had 24 points and 11 rebounds to lead No. 17 San Diego State to an 83-73 win over TCU on Saturday night, giving the Aztecs their seventh straight 20-win season.

James Rahon added 16, Chase Tapley 14 and DeShawn Stephens 13 for the Aztecs (20-3, 6-1 Mountain West). SDSU has seven 20-win seasons overall in 13 seasons under coach Steve Fisher, including last year's school-record 34-3 performance.

With No. 11 UNLV losing at Wyoming, the Aztecs regained sole possession of the conference lead.

Kyan Anderson had 22 points and J.R. Cadot 15 for TCU (13-9, 3-4), which lost its seventh straight to SDSU.

After shooting just 31.3 percent from the field in a 17-point loss at Colorado State and a two-point home win against Boise State, the Aztecs made 50.8 percent of their shots. Several nice dunks helped the Aztecs with the better percentage, including one when Franklin came flying in for a rebound and an impressive reverse slam that made it 39-31 in the first half.

SDSU outrebounded TCU 35-21.

San Diego State overcame an early deficit to take a 46-39 halftime lead, and then outscored the Horned Frogs 12-6 to start the second half. Franklin hit a bank shot and Tapley had a layup and two free throws to open the half. Franklin hit a jumper, Tapley had another layup and Garrett Green a reverse slam dunk to push the lead to 58-45 with 16:10 left.

TCU made four 3-point shots in the first 7:15 to take a 23-16 lead.

The Aztecs tightened their defense and went on a 17-4 run to jump ahead 33-27 with 4:46 before halftime. Franklin started the run with a dunk and Rahon added a 3-pointer.

Stephens had three points during the run and had six more the rest of the half, including consecutive baskets for a 37-29 lead.
