Baltimore’s Gervonta Davis stayed unbeaten in his career with a 12th-round stoppage of Yuriorkis Gamboa to win the WBA secondary lightweight title Saturday night.

Fighting past the ninth round for the first time, Davis (23-0, 22 KOs) showed why his nickname is Tank, releasing a barrage of punches in the final round before a left uppercut to the head ended the fight at the 1:44 mark when referee Jack Reiss called it. Davis, 25, who became a two-division champ in his adopted hometown, dropped Gamboa three times. He landed a left hand to knock the veteran down in the final seconds of the 8th.
