Saint Louis’ A-10 Tournament Run Ends in 70-69 Semifinal Loss to Dayton on Saturday

A one-point finish swings the bracket in Pittsburgh

Saint Louis’ Atlantic 10 Tournament season ended Saturday, March 14, with a 70-69 semifinal loss to Dayton in Pittsburgh. The Billikens, the tournament’s No. 1 seed, led 36-33 at halftime but were outscored 37-33 after the break as Dayton advanced to the championship game.

The semifinal was played on a national cable broadcast and drew an announced crowd of 8,523. With the result, Dayton moved one win from the league’s automatic NCAA Tournament berth, while Saint Louis shifted into the selection process with its postseason fate dependent on the broader at-large landscape.

How the matchup set up

The teams arrived at the semifinal with recent evidence pointing in both directions. Saint Louis had delivered an emphatic home win over Dayton on Jan. 30, 2026, posting 102 points in a lopsided result at Chaifetz Arena. Dayton answered later in the regular season, defeating Saint Louis 77-62 on Feb. 24, 2026, in Dayton—an outcome that helped frame the semifinal as a contrast of styles and momentum rather than a simple seed-line matchup.

• Jan. 30, 2026: Saint Louis 102, Dayton 71 (Chaifetz Arena)
• Feb. 24, 2026: Dayton 77, Saint Louis 62 (UD Arena)
• March 14, 2026: Dayton 70, Saint Louis 69 (A-10 semifinal, Pittsburgh)

Game flow: Saint Louis leads at the half, Dayton closes late

Saint Louis carried a three-point edge into intermission, but Dayton stayed within striking distance and produced the better scoring margin in the final 20 minutes. In a game that remained a one-possession contest deep into the second half, Dayton’s ability to keep pace early and then find incremental advantages after halftime proved decisive.

Halftime: Saint Louis 36, Dayton 33. Final: Dayton 70, Saint Louis 69.

What the result means going forward

For Dayton, the win secured a place in the Atlantic 10 championship game and kept the Flyers in position to claim the conference’s automatic NCAA Tournament bid. For Saint Louis, the loss ended a bid for the tournament title and turned attention to Selection Sunday outcomes. The Billikens’ profile now rests on their body of work across the full season, including results against conference opponents and performance away from home, rather than the additional résumé boost that would have come with a tournament championship.

The semifinal underscored the Atlantic 10’s postseason volatility: a top seed can control long stretches and still see its run end on a single late possession, with tournament margins small enough that each defensive stop and empty trip carries outsized weight.
