In UMBC’s 74-54 win over the Cavaliers, who came in as 20½-point favorites, the Retrievers built a seven-point lead before the first media timeout in the second half and saw the lead quickly climb behind senior guard Jairus Lyles, who scored 23 of his 28 points after halftime, as well as 5-foot-8 senior guard K.J. Maura, who dictated the pace at both ends, and sophomore forward Arkel Lamar, who had 12 points and 10 rebounds. It marked the first time since the tournament was expanded to 64 teams in 1985 — and eventually to 68 — that a No. 16 seed had beaten a No. 1 seed.
