This was supposed to be a get-well fight for Robert Guerrero, but David Peralta had other plans as he upsets Guerrero on his way to a split decision victory. All in all it wasn't the prettiest fight to watch, with long periods of inactivity and posturing, but Peralta was able to make some adjustments as the fight progressed while Guerrero wasn't and that ended up making the difference in the fight.
Specifically, Peralta utilized a sneaky right hand that he was able to land over and over again in the second half of the fight while Guerrero just had no answer for it. Guerrero seemed like a fighter a little confused with his style. He often switched from the typical mauling tactics we're used to seeing from him to laying back and letting Peralta come forward - which didn't exactly work out better for him.
Peralta now has the biggest win of his career in something he called the biggest moment of his life. He was clearly emotional after the fight knowing that he'll almost surely get another chance to fight on the big stage in the U.S., and truthfully he was a deserving winner.
What's more unclear is where Robert Guerrero goes from here. He's 2-4 in his last 6 fights and this is a pretty big setback for him. Losing to Danny Garcia, Keith Thurman, and Floyd Mayweather is one thing. Losing to an Argentine import who was basically brought in to lose is quite another...
