4 vs. 13 History


March Madness has finally arrived! Here we will examine the history of the 4 seed versus the 13 seed and deliver game lines for this year’s matchups. The No. 4 seeds are often those teams ranked between 12-20 in the final Associated Press poll. They are often teams from the power conferences or the best teams from the next tier of conferences. The No. 13 seeds are almost always from the smaller or non-power conferences, and most of them earned an automatic bid by winning their conference tournaments.

  • South: Illinois vs. Chattanooga +8

  • 4 seed — Illinois 54, 13 seed — Chattanooga 53
  • 4 seed — Providence 66, 13 seed — South Dakota State 57

The 2021 NCAA tournament was an all-timer in terms of upsets and two of the biggest came with 13 seeds taking down 4s. Thirteen-seed Ohio sprung an upset on Virginia and North Texas was the other 13 to prevail, beating Purdue.

The biggest opening round upset by seeding in the 2019 NCAA Tournament came in the 4 versus 13 match-up. In the South Region, Big West Conference champ and 13 seed UC Irvine (+3.5) took out Big 12 regular season co-champion Kansas State, 70-64. It was the Anteaters 17th straight win and 31st of the season. The other three No. 4 seeds won with two point spread covers. Kansas (-7) from the Big 12 rolled over CAA’s Northeastern, 87-53. Two teams from the ACC were winners with Virginia Tech (-10) beating Atlantic 10 entrant St. Louis, 66-52. Florida State (-8.5) held off American East champion Vermont, 76-69.

The No. 4 seeds went 3-1 SU and 2-2 ATS.

Virginia Tech and Florida State beat two No. 12 seeds in the Round of 32. Kansas lost by double digits to No. 5 and future Final Four entrant Auburn. And Cal Irvine was also a double-digit loser to No. 12 Oregon.

Both Virginia Tech and Florida State lost to No. 1 seeds in the Sweet Sixteen. Duke escaped at the buzzer to beat Virginia Tech 75-73, and Florida State was no match for Gonzaga, 72-58. 

Recall that the 2018 NCAA Tournament produced a pair of big upsets in the 4 vs. 13 match-up. Buffalo (+9) destroyed Arizona 89-68 and Marshall (+13.5) toppled Wichita State 81-75. The No. 13 seeded underdogs went 4-0 ATS.

No. 4 seeds are 69-19 versus No. 13 seeds since 2000 and are 117-31 in March Madness since 1985.

The biggest blowout came in 2013 when No. 4 seed Syracuse man-handled Montana 81-34 as a 13-point favorite.

The biggest margin upset by the underdog was in 1985 when David Robinson and No. 13 seed Navy crushed LSU 78-55. The other two blowout winners by 13th-seeded teams were Buffalo’s 2018 win over Arizona 89-68 and No. 13 Siena’s shocker over Vanderbilt 83-62 in 2008.

One of the most memorable moments in Nos. 4 versus 13 seeds in NCAA Tournament history was the buzzer-beater by No. 13 seed Valparaiso in 1998. Trailing 69-67 with 2.5 seconds remaining in regulation, Valpo inbounded the ball from its own baseline past midcourt. That player tapped the ball to guard Bryce Drew, the coach’s son, who nailed a 23-foot 3-pointer for the miraculous win.

The success of 4 and 13 seeds in March Madness

Since 1985, there have been 31 upsets of No. 13 seeds over No. 4 seeds with a record of 31-113. Six times a 13th-seeded team has advanced to the Sweet 16; most recently was LaSalle (2013) and Ohio (2012), who both lost.

There has never been a No. 13 seed advance to the Elite Eight.

In 1997, the Arizona Wildcats won the National Championship as a No. 4 seed and beat three No. 1 seeds to take the title. Two other No. 4 seeds have advanced to the National Championship game but lost.

No. 4 seeds have advanced to the Elite Eight 21 times and won 13, but those 13 No. 4 seeds are 3-10 in trying to reach the Final Four.
