Solo Boxeo Tecate: Windy City Fight Night 18 salutes fans in a card stuffed with intense fisticuffs, eschewing cheesy theatrics for meaty, primal pounding as a dozen boxers duke it out in exciting bouts. During the main event, Illinois favorite Adrian “El Tigre” Granados will dispute the finer points of pugilistic philosophy in a multiround debate with East LA’s Frankie Gomez. Granados, a Cicero, Illinois, native, has been a favorite of Chicago fight fans since his professional debut in 2008. A student of Hall of Fame trainer Nacho Beristain, Granados draws huge crowds with his action-packed performances that are all knuckles and no anguished interior monologue. At the tender of age 19, Gomez already has one foot in the Wheaties box, having destroyed every opponent in his first 10 professional bouts, eight by knockout and two by excessive tickling. Filling up the rest of the gale-force evening, five undercard bouts between vicious heavy hitters such as Daniel Sotelo and Luis Santiago will keep the bruises flowing.
