MINNEAPOLIS – Alfredo Santiago emphatically came back Saturday night from his own knockout loss to Ricardo Nunez last year.

Santiago overpowered Karl Dargan and stopped him in the first round of a lightweight fight that was scheduled for 10 rounds on the non-televised portion of the Stephen Fulton-Daniel Roman undercard at The Armory. The Dominican Republic’s Santiago stopped Philadelphia’s Dargan just 1:21 into their fight and became the first fighter to knock out Dargan in 22 professional fights.

Referee Ricky Gonzalez stepped between them to stop the bout because Dargan wasn’t throwing punches back at Santiago.

The 27-year-old Santiago hadn’t fought in more than a year, not since Nunez, a Panamanian power puncher, stopped him in the ninth round last May 21 in Panama City. Santiago’s only previous loss was a 12-round unanimous decision to WBC world lightweight champion Devin Haney (27-0, 15 KOs), who was readying to square off against Australia’s George Kambosos Jr. (20-0, 10 KOs) in a full 135-pound championship unification fight on Sunday afternoon at Marvel Stadium in Melbourne.

The 36-year-old Dargan’s only loss before Saturday night was a 10-round unanimous decision to Canada’s Tony Luis in January 2015 at Foxwoods Resort Casino in Ledyard, Connecticut.
