A previously unknown underdog promoted by Marcos Maidana ended one of the longest championship reigns in boxing Saturday night.
Argentina’s Fernando Martinez upset the Philippines’ Jerwin Ancajas by unanimous decision in a brutal, entertaining 12-round, 115-pound championship match that opened Showtime’s tripleheader from The Chelsea inside The Cosmopolitan of Las Vegas. Judges Max De Luca (117-111), David Sutherland (118-110) and Steve Weisfeld (118-110) favored a determined Martinez’s aggression, activity and accuracy and rewarded him with by far the most noteworthy win of his career.
The 30-year-old Martinez (14-0, 8 KOs) won the IBF junior bantamweight championship that Ancajas had owned since September 2016. Ancajas (33-2-2, 22 KOs), who was a 5-1 favorite according to Casears Sportsbook, had made nine successful defenses of his IBF belt before Martinez beat him.
Ancajas, also 30, has a rematch clause in his contract for this optional title defense against the 11th-ranked Martinez. He told Showtime’s Jim Gray in his post-fight interview that he will make use of that contractual right.
The former champion had hoped to face Japan’s Kazuto Ioka, the WBO junior bantamweight champion, in a title unification fight during the summer.
According to Showtime’s punch stats, Martinez landed 427 of an eye-catching 1,046 punches. Ancajas connected on 192 of 816 punches.
