LAKE BUENA VISTA, Fla. — Elias Harris and Kelly Olynyk each scored 13 points to help No. 17 Gonzaga beat Clemson, 57-49, in a first-round game Thursday night at the Old Spice Classic.

Olynyk was in the starting lineup after missing the previous three games due to a violation of the student code of conduct. The junior forward, who had his first two shots blocked, also had three rebounds.

Clemson got 10 points from Adonis Filer. Milton Jennings had six points and eight rebounds.

Sam Dower had 11 points for Gonzaga (4-0), which will go against Oklahoma in today’s semifinals. Clemson (2-1) will face Texas-El Paso in the loser’s bracket.

David Stockton had an end-to-end layup, while Kevin Pangos and Harris added in-close baskets as Gonzaga went ahead 47-39 with 61/2 minutes to play.

Harris’ 3-point play two minutes later made it 50-41.
