Relive ONE Championship titleholder Ben Askren's retirement fight in photos

ONE Championship welterweight titleholder Ben Askren put an exclamation point on his MMA career with one final dominant performance in his retirement fight.

Askren (18-0) needed just 57 seconds to score a TKO win over Japanese notable Shinya Aoki (39-8) in the main event of today’s “ONE Championship 65: Immortal Pursuit.” The event, which took place at Singapore Indoor Stadium, streamed as an online pay-per-view in North America.

Askren, 33, leaves behind a decorated MMA career that includes an undefeated record with long title reigns in both ONE and Bellator before that.
