She may be a grandmother – the younger of her two children, Omar (18) and Yadira (17), recently gave birth to a baby girl – but Gloria Ríos [4-3-2 (0 KOs)] of El Queso, who will be disputing the Mexican Bantamweight and vacant NABF Super Flyweight titles with Ana Marïa Torres of Ciudad Nezahualcóyotl at the Nueva Atzacoalco sporting club on Saturday, has enough gas, she tells us, to go fifteen rounds – which at today's prices, makes her not simply rich but in the J. Howard Marshall II class in terms of eligibility!

Four times thwarted by Delia López in her bid for the junior flyweight title – though the two draws, she feels, should really have been wins for her – the 34-year-old, whose tattoos hark back to her days running with a girl gang, has trained hard, but dismisses questions about strategy with a blasé (going on lackadaisical) shrug: "I haven't seen her fight," she says of Torres [12-1-1 (8KOs)], who has twice been voted Mexican Boxer of the Year and whom WBAN ranks 8th in the world. "I'll fight her whichever way she wants."
