Isaiah Watts and Andrej Jakimovski scored 18 points each and Myles Rice added 16 to help No. 19 Washington State rally past Southern California 75-72 on Thursday night. The Cougars (22-7, 13-5 Pac-12) trailed by 12 points late in the first half and didn’t take their first lead until 2:35 remaining on a 3-pointer from Watts, his fifth of the game. Washington State avoided what would have been its second straight loss to an unranked opponent after winning at No. 4 Arizona on Feb. 22.
