Robeisy Ramirez impressively continued his comeback Tuesday night from a shocking loss in his professional debut.

Ramirez knocked down Yeuri Andujar twice within the first minute of their scheduled six-round featherweight fight and knocked him out in the first round at MGM Grand Conference Center in Las Vegas. The 26-year-old Ramirez, a two-time Olympic gold medalist from Cuba, won his third straight fight since Adan Gonzales beat him by split decision in his pro debut, a four-rounder August 10 in Philadelphia.

Ramirez’s victory was the first boxing match televised in the United States since the COVID-19 pandemic essentially shut down the boxing business in the middle of March.

The left-handed Ramirez (3-1, 3 KOs) buckled Andujar’s legs with a left hook less than 30 seconds into their fight. He sent Andujar to the canvas with a left uppercut soon thereafter, exactly 30 seconds into the opening round.

Andujar got up, but clearly was still hurt. Another left hand by Ramirez dropped Andujar, which caused referee Tony Weeks to immediately wave an end to their fight, 54 seconds into it.

The Dominican Republic’s Andujar slipped to 5-4. He lost by knockout for the second time.

ESPN televised Ramirez’s victory on the Shakur Stevenson-Felix Caraballo undercard. Ramirez edged Stevenson, the WBO featherweight champion, in the bantamweight gold medal match at the 2016 Summer Olympics in Rio de Janeiro.
