An overhand right from Kudo shut the lights off on Flores at the 2:52 mark of the first round, guaranteeing the Japanese vet a spot in the playoffs with a six-point finish.
Check out the finish below.
Kudo joined Brendan Loughnane, who opened the card with a decision win over Ago Huskic, Sheymon Moraes and Chris Wade on the leaderboard in the regular-season event.
PFL 5 took place at OTE Arena in Atlanta and aired on ESPN+.
Kudo also got back to the win column after a loss to Loughnane in his first 2022 PFL appearance. In that fight, his punching power made itself known early when he hurt the U.K.-based fighter on several occasions; wrestling proved to be his downfall in a 15-minute contest.
Flores goes back to the drawing board after wins in his first two PFL outings.
