LONDON (AP) — Katie Taylor's biggest rival believes the Irish lightweight boxer gets much more help than she deserves from referees, judges and even the highest levels of the amateur sport.

Sofya Ochigava of Russia will fight Taylor on Thursday for a gold medal in the debut of Olympic women's boxing after both won their semifinal bouts Wednesday.

Ochigava is fed up with losing to Taylor in international competitions, most recently in the world championships in May.

The Russian says opponents begin with "minus-10 points" against Taylor, who is "protected" by AIBA.

Ochigava thinks the referees and judges shouldn't reward Taylor for her past achievements, including four consecutive world titles. The Russian says she feels as if she's boxing all five judges at ringside along with Taylor.
