HOUSTON — Anthony Dell’Orso tied a season high with 22 points and No. 4 Arizona toppled second-ranked Houston 73-66 on Saturday to move into sole possession of first place in the Big 12 Conference.

Arizona (25-2, 12-2), which opened the season 23-0, won its second straight game following consecutive losses to then-No. 9 Kansas and then- 16th-ranked Texas Tech, that knocked the team out of the No. 1 spot in the AP Top 25 poll.

The Wildcats were down by two before scoring the next 12 points to make it 60-50 with about five minutes remaining. The Cougars missed eight consecutive shots and had three turnovers in that stretch to allow Arizona to build the lead.

Houston (23-4, 11-3) hadn’t scored in about eight minutes when Emanuel Sharp made two free throws with 4 ½ minutes to go. Kalifa Sakho made two more free throws to cut the lead to 60-54 with less than four minutes remaining.

It had been more than 10 minutes since the Cougars made a field goal when a 3-pointer by Kingston Flemings got them within 61-57, but Arizona got four straight points by Jaden Bradley to pad the lead with just over a minute left.

Flemings had 17 points and Sharp added 14 for the Cougars, who lost consecutive games for the first time this season after falling 70-67 at No. 6 Iowa State on Monday night to end a six-game winning streak.

The Cougars struggled to take care of the ball, committing 12 turnovers that led to 16 points for the Wildcats.
