Eduardo Ramirez is on a roll.
The Mexican, coming off an impressive stoppage of Leduan Barthelemy 13 months ago, knocked out Miguel Flores with a single right hook in the fifth round on the Errol Spence Jr.-Danny Garcia card Saturday in Arlington, Texas.
The fight was designated as a 126-pound title eliminator.
Ramirez (24-2-3, 10 KOs) isn’t known as a puncher but he can box, as he demonstrated in four-plus rounds at AT&T Stadium.
The 27-year-old southpaw controlled the fight from the outset, dictating the pace, beating Flores to the punch, outworking him and landing the bigger shots to win the first four rounds on the Boxing Junkie card.
Flores (24-4, 12 KOs) had his moments, particularly in a competitive fourth round that seemed to give him hope of climbing back into the fight. In particular, he landed some hard, eye-catching body shots that Ramirez felt.
However, only seconds in Round 5, Flores was throwing a straight right when he got caught with a vicious right hook that put him on his back. He got up at the count of seven but turned away from referee Laurence Cole and stumbled, prompting Cole to wave off the fight.
The official time was 20 seconds into the round.
Flores was a late replacement for Julia Ceja, who had to pull out after testing positive for COVID-19.
