(BCSNN) - The Alamo Bowl has a way of turning TCU quarterbacks into legends. On Friday night, in his first start and final game as a Horned Frog, Ken Seals added his name to the lore.

Seals rallied TCU from a 10‑point fourth‑quarter deficit and delivered a 30–27 overtime victory over No. 16 USC, punctuated by one of the most electrifying bowl finishes in program history. Facing 3rd‑and‑20 in the first overtime, Seals dumped a short pass to running back Jeremy Payne - and Payne did the rest, slipping four would‑be tacklers, tight‑roping the sideline, and sprinting into the end zone to ignite a purple‑clad crowd inside the Alamodome.

The win moved TCU to 3–0 all‑time in the Alamo Bowl, each victory coming after trailing by at least 10 points. The legend grows.

The game began slowly as Seals and first‑time playcaller Mitch Kirsch settled in. USC opened the scoring with a field goal, but Seals responded by leading a second‑quarter touchdown drive to give TCU its first lead. He added another score with his legs, putting the Frogs ahead 14–10 before a pair of key pass breakups by Bud Clark helped TCU take a 14–13 lead into halftime.

USC grabbed momentum early in the third quarter with an interception, but Channing Canada answered with an end‑zone pick of his own to preserve the lead. Still, TCU sputtered offensively, managing just 35 yards - fewer than its 40 penalty yards - in the third quarter. USC capitalized, building a 24–14 advantage with 9:37 remaining.

That’s when Seals and Payne took over.

TCU marched 75 yards in 11 plays, capped by Payne’s first touchdown of the night to pull within 24–21. On USC’s next possession, Jayden Maiava - who had already connected with freshman standout Tanook Hines for 163 yards - tried to hit Hines again to ice the game. But TCU freshman Gil Jackson broke up the pass, forcing a punt and giving the Frogs one more chance.

Seals delivered again, guiding a 13‑play, 59‑yard drive that ended with Kyle Lemmerman’s 27‑yard field goal as time expired to tie the game at 24–24 and force overtime.

After USC managed only a field goal on its overtime possession, Seals faced 3rd‑and‑20 with the game on the line. His check‑down to Payne turned into a play that will live in TCU lore - a weaving, tackle‑breaking, sideline‑hugging sprint that sealed the win as former Alamo Bowl hero Bram Kohlhausen watched from the sideline.

New legends of the Alamo, indeed.
