CHARLOTTE, N.C. — UMBC made NCAA tournament history Friday night.

The University of Maryland-Baltimore County, the America East tournament champion, became the first No. 16 seed to beat a No. 1 seed with a 74-54 victory against Virginia.

This was a shocker.

Virginia (31-3) was the unanimous No. 1 team in the AP poll.

They were no match for the Retrievers (25-10), especially after halftime. The score was 21-21 at the half.

UMBC wasn’t even the America East regular-season champion, finishing second to Vermont, then stunning the Catamounts with a last-second 3-pointer in the tournament final last Saturday.

Virginia couldn’t get anything generated on offense, and the nation’s top-ranked defense allowed its most points this season.

Senior guard Jairus Lyles was the catalyst.

He diced up Virginia’s defense in the second half, getting to the basket easily on six different occasions and making easy layups. He also knocked down a pair of 3-pointers as UMBC built a 16-point lead.

Lyles scored 23 of his 28 points in the second half, and Joe Sherburne finished with 14 points.

The game was tied at halftime, but the Retrievers came out confident and motivated in the second half and built a double-digit lead that Virginia could never erase.

Sherburne scored on an and-one drive and then knocked down a 3-pointer from the top of the key after a behind-the-back pass from KJ Maura. After Virginia made a foul shot, the shifty 5-foot-8, 140-pound Maura drove the lane for uncontested layup.

A Tony Bennett timeout couldn’t stop the bleeding, as Lyles hit two more 3’s and Sherburne hit one to extend UMBC’s lead to 14 with 14:57 left in the game. Lyles was fouled on a 3-point shot and suddenly the Retrievers led by 16.

A corner 3-pointer and a layups off a fastbreak by Arkel Lamer gave UMBC its biggest lead at 67-48. From there, the party was on as chants of “UMBC” rang through the arena.

It was yet another early exit for the Cavaliers in a season that seemed to hold so much promise.
