TALLAHASSEE, Fla. — New quarterback Tommy Castellanos led a punishing rushing attack for Florida State with 78 yards and a touchdown as the Seminoles stunned No. 8 Alabama 31-17 on Saturday, ending the Crimson Tide’s streak of 23 straight wins in season openers.

Coming off a 2-10 season, Florida State handed a crushing setback to Alabama, which was viewed as a College Football Playoff contender under second-year coach Kalen DeBoer.

Castellanos, a transfer from Boston College, made headlines over the summer after saying legendary Alabama coach Nick Saban wasn’t there to “save” the Tide vs. Florida State in their Week 1 matchup and that he doesn’t “see them stopping me.” He backed up that jab by spearheading FSU’s dominant ground attack while staying efficient through the air, finishing 9 of 14 passing for 152 yards.

Students and fans swarmed the field at Doak Campbell Stadium to celebrate the upset by the Seminoles, who closed as 13½-point underdogs at ESPN BET.

Under new offensive coordinator Gus Malzahn, who spent eight seasons as Auburn’s head coach, Florida State was physical from the start, finishing with 230 rushing yards and averaging 4.7 yards per carry. The Seminoles averaged just 89.9 yards during their disastrous 2024 season.

The Crimson Tide had not dropped a season opener since losing 20-17 to UCLA in 2001 under Dennis Franchione, and this defeat will ratchet up the pressure on DeBoer from the demanding Tuscaloosa faithful. His predecessor, Nick Saban, led Alabama to six national titles.
