The Tigers (6-2) led by as many as nine points midway through the fourth period, but Marquette (4-5) knocked down three 3-pointers in the final 1:20, including a tying basket with eight seconds left. Meanwhile, the Tigers went cold at the free-throw line and were unable to ice the game despite several opportunities late.
"Foul trouble, missed layups, we go 13-for-30 at the free-throw line, we gave the game away," Auburn head coach Terri Williams-Flournoy said. "It was our game so many times, we just gave it away. We had so many opportunities. It was ours to win. But we missed layups and we missed free throws. That's the ballgame right there."
Tied 60-all at the end of regulation, Marquette jumped out to a five-point lead in overtime, but a Cabriana Capers layup cut it to a one-possession game at 69-66 with 1:29 to play. After each team went 1-of-2 on free throw opportunities in the final minute, Auburn had the ball down by three with 16 seconds left. However, no one could get open for a 3-point try, and a Capers layup off a missed attempt with less than a second to go made the final margin 70-69.
Montgomery recorded her second career double-double with 24 points and 12 rebounds, scoring 13 points in the fourth quarter to give Auburn its biggest lead. Tanner recorded her third double-double of the season with 13 points and 12 rebounds.
It was the first time for two Auburn players to have a double-double in the same game since Peyton Davis and Tyrese Tanner did so at Alabama A&M in 2013.
As a team, Auburn had a season-high 57 rebounds with 23 of those on the offensive glass, but had their worst shooting day of the season at 32.5 percent from the field. The difference in the game, however, was free-throw shooting: Auburn was 13-of-30 at the line, including 4-of-14 in the second half and 3-of-6 in overtime. Marquette was not much better at 14-of-26, but the Golden Eagles hit 5-of-7 attempts in the extra period. Marquette shot 37.1 percent from the field for the game.
The Tigers' depth took several hits throughout the game, and Auburn was missing three starters by overtime. Starting point guard Khady Dieng suffered a shoulder injury in the first quarter and did not return, Jazmine Jones fouled out with just over two minutes left in regulation, and Katie Frerking picked up her fifth foul early in the overtime period. Marquette dealt with foul trouble, too, but of their six players that had at least four fouls, only one fouled out.
McKayla Yentz led Marquette with 16 points, and Allazia Brockton had 10 points and 12 rebounds.
The Tigers are back at Auburn Arena for the inaugural Education Day game vs. Winthrop, which tips off at 11 a.m. Wednesday, Dec. 16.
