Amanda Serrano demands respect for all she has done for women’s boxing, a seven-division champion who’s now tied with legend Christy Martin for the most knockouts in the sport’s history.

When featherweight title challenger Cheyenne Hanson of Germany chose to blow a bubble gum bubble at Serrano during the face-off, Serrano viewed it as a disrespectful act.

Saturday night at the sold-out El Paso Civic Center in Texas, Serrano 49-4-1 (32 KOs)  made Hanson pay, stopping Hanson by TKO 2 minutes, 25 seconds into the second round.
