Scorecard: Time for Deontay Wilder to step up in competition

— -- A roundup of the past week's notable boxing results from around the world:

Sunday at Osaka, Japan

Kazuto Ioka W12 Roberto Domingo Sosa
Retains a flyweight title
Scores: 120-108, 119-109 (twice)
Records: Ioka (18-1, 10 KOs); Sosa (26-3-1, 14 KOs)

Rafael's remarks: Japan's Ioka, 26, was fighting in his hometown and making the first defense of the secondary title he won by majority decision against Juan Carlos Reveco, also in Osaka, on April 22. Ioka, who is due to face Reveco in a rematch later this year, routed Sosa, 30, of Argentina, who lost his second shot at a world title. He also dropped a decision to Juan Carlos Sanchez Jr. for a vacant junior bantamweight title in 2013 (after Sanchez had been stripped for being overweight). Ioka, a two-time flyweight titleholder and former unified strawweight titlist, had too much speed and movement for the one-dimensional Sosa. Ioka counter punched Sosa with ease and made him miss almost everything of consequence. Ioka's biggest punch may have been in the 12th round when he hurt Sosa with a body shot.

Katsunari Takayama TKO8 Ryuji Hara
Retains a strawweight title
Records: Takayama (30-7, 12 KOs); Hara (19-2, 11 KOs)

Rafael's remarks: Japan's Takayama, 32, who was fighting in his hometown, made the second defense of his belt against countryman Hara, 25, who has now lost two of his last three bouts. The faster Takayama blitzed Hara with punches from all angles throughout the fight. Hara landed some good shots, but most of them in the first few rounds before he began to slow down. An accidental head-butt opened a cut over Takayama's left eye in the third round, which bled for most of the rest of the fight. The cut did not seem to impact Takayama's zeal for combat as he continued to take it to Hara with his quick punches. He had him in trouble in the seventh round and then finished him in the eighth round. Takayama teed off on Hara in the eighth, landing numerous overhand right hands and bullying him along the ropes. Hara had no answers and as Takayama continued to pound away at a defenseless Hara, referee Wayne Hedgpeth stepped in to call it off at 1 minute, 20 seconds.

Takayama, who led 69-64, 68-64 and 68-65 at the time of the stoppage, won his third fight in a row since a losing a decision to Francisco Rodriguez in an epic strawweight unification fight 13 months ago that was the picked as the 2014 ESPN.com fight of the year. In his next fight, Takayama won two belts, both of which Rodriguez vacated after their fight in order to move up in weight. Takayama then vacated one of them.

Saturday at Bahia Blanca, Argentina

Juan Carlos Reveco W10 Breilor Teran
Junior bantamweight
Scores: 100-90 (twice), 99-91
Records: Reveco (36-2, 19 KOs); Teran (14-13-1, 7 KOs)

Rafael's remarks: On April 22, Reveco, 32, of Argentina, lost a majority decision and his flyweight world title to Kazuto Iola in Japan. In his first bout since the defeat, he returned to face soft touch Teran, 30, of Venezuela, who lost for the fourth time in his last five bouts (all by decision). Reveco easily outboxed Teran on his way to a virtual shutout decision. One judge gave Teran a single round. The victory paved the way for Reveco to return to Japan later this year to face Ioka in a rematch.
