Jeison Rosario ruined Julian Williams' homecoming on Saturday night.
In Williams' hometown of Philadelphia, Rosario stunned the heavily favored fighter to become the unified WBA/IBF junior middleweight champion.
Williams entered the fight as a 30-1 favorite, but Rosario bloodied him early on and he couldn't recover, falling to the Dominican after a referee stoppage in the fifth round.
Rosario moves to 20-1-1 following his shocking victory, and Williams' record drops to 27-2-1 after the loss.
