Caroline Dubois: The Briton retains the world title with a dominant display against Camila Banat

Dubois fought back early in the night in front of a lightly packed Casilla Center — home of the 20,000-seat Miami Heat.

She walked to the ring singing along to Whitney Houston’s “I’m Every Woman” and started confidently, moving in and out of range and hitting the piñata repeatedly.

She landed a straight left from the champion southpaw’s stance cleanly and regularly in the third round as the gap in class became increasingly apparent.

“Beautiful, Caroline, keep going,” his stablemate and former cruiserweight world champion Chris Pillam-Smith shouted from the crowd as Dubois stepped forward.

Dubois hit a body shot to the midsection of a panatta in the fifth and again in the sixth, each drawing approving nods from ringside.

Moments later, the final blow came. When Panatta dropped back to attack the body, Dubois took the shot and fired a perfectly timed counter shot to the chin.

Panatta, 34, hit the canvas in a heap.

She rose quickly but seemed shaken; Her short smile did little to hide the impact of the punch.

With little time left in the round, Panatta was able to see the bell.

Dubois increased the intensity in the closing stages, varying her action by mixing jabs and uppercuts, while the signature Panatta had little to answer as the champion finished the final rounds comfortably.

This meant that there was little doubt when the scorecards were read.
