Peters and Walker, a junior college transfer playing in his first game for Valparaiso, combined to make 9 of 13 from 3-point range. The Crusaders shot 55.6 percent from 3-point range and made 26 of 52 field goals.
A layup by Desonta Bradford pulled ETSU within 3 with 5:01 to play, but Walker and Peters hit back-to-back 3-pointers - sandwiched around a missed 3 by Bradford - to make it 78-69 and the Buccaneers, who were 0 for 7 from the field in the final 5 minutes, would never threaten again.
Valparaiso made more free throws (28) than ETSU attempted (23).
Jalen Riley led ETSU with 27 points.
