The rounds were close...
Casimero started off well in the bouth pressuring more and coming forward.
Midway though Garcia figured him out and started countering well.
Garcia then attacked the body for several rounds and IMO that's what made the difference. He hurt Casimero to the body and started pushing Casimero back.
Garcia also closed out the fight stronger and that also gave him the nod.

With that being said, this was def. a different Casimero then the one who fought Canchilla.
As for Garcia he has so much to improve on if he want's to keep that belt.

Both Calderon and Segura beat him IMO...
