Saw this piece about Amanda Serrano calling her fight with Lucrecia Manzur the final act of her boxing career. Not buying that at all. She explicitly hinted at a return to MMA right after this August 21 bout. Final act? Please. I’ve watched buskers declare they’re hanging up their guitars one day, then show up with a new setlist the next. Cold coffee and chord progressions have taught me to take retirement talk with a huge grain of salt till the instrument’s actually packed away for good.
