WACO, Texas— Davion Mitchell had 17 points, scoring just before and after halftime as No. 2 Baylor started stretching its lead, and the Bears beat Iowa State 68-55 on Wednesday night for their 13th win in a row.

Rasir Bolton and Prentiss Nixon both had nine points for Iowa State (8-8, 1-3 Big 12).

Jared Butler had 19 points and five assists to lead the Bears, whose only loss came against Washington in Alaska the first week of the season. They had road wins last week against at No. 23 Texas Tech and No. 6 Kansas, that win at Allen Fieldhouse being their first ever there.

After Baylor made only 1-of-11 3-pointers before halftime, Mitchell hit from long range in the first minute of the second half. Another 3 by Mitchell less than two minutes later stretched the lead to 38-25.

The Bears had a 30-25 halftime lead after Mitchell's three free throws with less than a second remaining. He took an inbound pass after Bolton's free throw with four seconds remaining and was fouled by Tre Jackson when taking a rushed shot from the right wing.

Vital had a slam dunk with just over five minutes left in the first half, but his turnover led to a fastball layup by Zion Griffin to put the Cyclones up 18-17 —their last lead.

Mitchell had a go-ahead layup with 4:02 left, and he then grabbed a defensive rebound and passed to Butler for a 3-pointer.
