SALT LAKE CITY — Unheralded Santa Clara held Arizona to only one field goal for 15 minutes of the second half Thursday night to send the second-seeded Wildcats to their second straight first-round loss in the NCAA tournament, 64-61.
Pete Eisenrich scored 19 points as the Broncos (19-11) became only the second 15th-seeded team to win a first round game in NCAA tournament history. Richmond beat second-seeded Syracuse 73-69 in 1991.
In a game of scoring streaks and droughts, Santa Clara overcame a 25-0 run and came back from a 13-point deficit in the second half to pull the biggest upset of this year's tournament.
It was the second straight first round upset loss for Arizona (24-4), which was knocked off by 14th-seeded East Tennessee State last year.
