Somewhat compelling match-up headlining ESPN+ in Cancún this Friday night. Mosquera is a talented, athletic southpaw but is clearly the B-side here, a natural 140lber going up at the age of 31 against quite a large welter in 25yo (and still filling out) Ellis...and he already has three stoppage losses, so that is where par is set for the undefeated American with the 19-0 (13) record if he wants to impress here.
I imagine Ellis will attempt to sit down on his shots a bit here as Mosquera's durability issues are so well known
