SEATTLE (AP) — Kyle Wiltjer scored 13 of his 24 points during Gonzaga’s flawless first half, Domantas Sabonis added 18 points and the second-seeded Bulldogs advanced to the round of 16 for the first time since 2009 with a 87-68 win over No. 7 seed Iowa in a South Region matchup on Sunday.

After five straight departures on the first weekend, the Bulldogs (34-2) are back in the regional semifinals, thanks to efficient offensive performance in the first 20 minutes that Iowa could never overcome. Wiltjer made his first six shots before finally missing a 3-point attempt midway through the second half. Sabonis added eight in the first half, including a thundering left-handed dunk that was followed by a scream that had KeyArena roaring just like Gonzaga’s home gym.

Jared Uthoff led Iowa (22-12) with 20 and Aaron White added 19.
