Claressa Shields outclasses Maricela Cornejo with ease to retain undisputed middleweight title

Shields proved to be too much for the short-notice opponent on Saturday night

When you're as good as Claressa Shields, dominant wins are simply an expected part of the job. Shields held up her end on Saturday, dominating Maricela Cornejo in Shields' backyard of Detroit to remain undisputed middleweight champion.

Cornejo stepped into the fight on short notice, replacing Hanna Gabriels after Gabriels failed a pre-fight drug test. The opportunity to become undisputed champion was worth the risk of not having full preparation for the bout for Cornejo, who entered the fight as a massive underdog.

Unsurprisingly, Shields -- the greatest female boxer in history -- dominated the action from the opening bell.
