Late block helps Arizona survive upset bid by Memphis
TULSA, Okla. -- Derrick Williams had 22 points and 10 rebounds, and blocked a potential tying shot in the final seconds to seal Arizona's 77-75 win over Memphis in the second round of the NCAA Tournament on Friday. Joe Jackson hit the first of two free throws with 5 seconds left, then missed the second to give the 12th-seeded Tigers a shot at the tie. Wesley Witherspoon grabbed the offensive rebound at the right block, but Williams came over to swat it away.
