The History of No. 13 vs No. 4

Over the past 40 years, since the NCAA Tournament field was expanded to 64 teams in 1985, 26 tournaments have seen at least one 13-seed triumph. In four of those years, multiple 13 seeds won games, including Xavier and Missouri State in 1987, Indiana State and Kent State in 2001, Siena and San Diego in 2008, and Buffalo and Marshall in 2018.

The 2008 upsets were particularly noteworthy, as both occurred on the same court in Tampa, making it a historic day in NCAA Tournament history. The other two winning teams that day were double-digit seeds: 12th-seeded Western Kentucky won on a buzzer-beater in overtime. And then, 12th-seeded Villanova staged a comeback from an 18-point deficit to upset Clemson.
The first time a 13 seed defeated a four seed was also memorable. In 1985, the inaugural year of the expanded tournament, future NBA star David Robinson led his Navy Midshipmen to a dominant 23-point victory over No. 4 seed LSU, which still stands as the largest margin of victory for any 13 seed.

Some Memorable No. 13 Over No. 4 Upsets

No. 13 Valparaiso 70, No. 4 Ole Miss 69 – March 18, 1988

Who could forget Bryce Drew’s incredible buzzer-beater that propelled Valpo past Ole Miss in the NCAA Tournament opener? Widely considered one of the most beautifully orchestrated buzzer-beaters in tournament history, the shot helped the Crusaders advance to the second round, where they defeated the 12th-seeded Florida State to reach the Sweet 16. Unfortunately, their run ended there with a loss to Rhode Island. Nevertheless, Drew’s unforgettable shot remains a cherished moment in NCAA Tournament lore. Bryce Drew is currently the coach at Grand Canyon, a 14 seed this year that is taking on Gonzaga in the first round.

No. 13 Richmond 72, No. 4 Indiana 69 – March 13, 1988

In 1991, coached by Dick Tarrant, the Spiders became the first No. 15 seed to win a game in the tournament, stunning 2-seed Syracuse. But this wasn’t the first time Tarrant had orchestrated an upset; in 1988, the Spiders knocked off defending national champions Indiana in the opening round, then upset fifth-seeded Georgia Tech in the second round. This was just the fourth 13-seed to knock off a four-seed. Richmond’s historic run ended in the Sweet 16, as top-seeded Temple handed them a 22-point defeat. Despite the loss, Tarrant and the Spiders had etched their names in NCAA Tournament history.
