ST. LOUIS (Interstat) — A dominant second-half surge by Saint Louis, fueled by relentless interior scoring and a decisive advantage in transition, overwhelmed San Francisco for an 85-75 victory in a nonconference men’s basketball game Saturday night at Chaifetz Arena.

A crowd of 5,814 watched the Billikens improve to 9-1, while the Dons fell to 6-5.

The game’s pivotal stretch came early in the second half, transforming what had been a tightly contested affair into a comfortable Saint Louis lead. After taking a narrow 31-30 edge into halftime, the Billikens erupted with a 14-2 run over the first four minutes of the second period. The burst was emblematic of the game’s defining themes: Saint Louis’s command in the paint and its ability to capitalize on turnovers.

Dion Brown, who finished with 14 points, ignited the run with a layup off a Robbie Avila assist. Amari McCottry, who led Saint Louis with 18 points, added a layup of his own. The sequence was capped by another Brown layup, forcing a San Francisco timeout with the Billikens ahead 45-32. Saint Louis scored 46 points in the paint for the game, more than doubling the Dons’ output of 22, and outscored San Francisco 12-3 on fast breaks.

San Francisco, which shot just 40.3% from the field, struggled to find consistent offense outside of guard Ryan Beasley. The sophomore from San Ramon, California, kept the Dons within striking distance with a game-high 21 points, including three 3-pointers. Tyrone Riley added 17 points for San Francisco.

Every time the Dons threatened to cut into the deficit, Saint Louis had an answer, often from a different contributor. When Beasley hit a 3-pointer to pull San Francisco within 49-44 with 13:44 remaining, the Billikens responded with a 9-2 spurt. That run featured a 3-pointer from Quentin Jones, who had five points, four assists and two blocks, and a 3-pointer from Brady Dunlap, who had eight points.

The Saint Louis offense operated with high efficiency, scoring 85 points on 73 possessions for an offensive rating of 116.6. The Billikens shot 48.4% from the field and were aggressive in getting to the free-throw line, making 18 of 25 attempts. San Francisco managed an offensive rating of 104.2, shooting 25 of 62 overall and 10 of 36 from beyond the arc.

Beyond McCottry and Brown, Saint Louis showcased its depth. Ishan Sharma scored 10 points with three assists, Kellen Thames added 10 points, and Avila chipped in nine points and three assists. The Billikens shared the ball effectively, tallying 18 assists on 30 made field goals, and matched San Francisco’s nine turnovers while forcing nine of their own.

The Dons, coming off a road win at Mississippi State, could not replicate that defensive intensity. They were outrebounded 40-35 and allowed Saint Louis to score 14 points off turnovers. The Billikens’ defensive pressure, which generated eight steals, disrupted San Francisco’s rhythm and fueled their transition game.

Saint Louis, which entered the game as an 11-point favorite according to sportsbooks, saw the total score of 160 surpass the over/under line of 148.5. The Billikens’ national statistical ELO projection gave them a 56.6% probability to win.

San Francisco will look to rebound quickly as it travels to face Loyola Chicago on Wednesday. Saint Louis continues its homestand Wednesday against Bethune-Cookman.
