It appeared to be a disappointing season-opening game for No. 20 USC against Arizona State on Saturday in Pasadena, and then the final three minutes happened.

Trailing 27-14, USC had 4th-and-13 at 26-yard line, when a Kedon Slovis pass was tipped in the end zone and fell into the hands of Bru McCoy for a Trojans touchdown.

And on the ensuing kickoff, USC recovered an onside kick.

With just over a minute remaining, USC once again turned a lengthy fourth down into a touchdown. Slovis connected with Drake London for a 21-yard score to tie the game, and USC then made the extra point that would serve as the game-winner in a 28-27 victory.

So, USC got a 4th-and-13 touchdown, an onside kick, and a 4th-and-9 touchdown, all in a two-minute span. Arizona State even had a 99.9% win probability with just over three minutes remaining.

An extremely improbable comeback victory for the Trojans, and a loss that will have Herm Edwards and the Sun Devils kicking themselves.
