BAKU, Azerbaijan -- Sixteen-year-old Marina Doi added to her growing collection of international wrestling medals on Thursday by earning gold medal at the 2012 Cadet World Championships in Baku, Azerbaijan in women's freestyle at 38 kilos.

Doi's victory in the gold-medal match came over returning Cadet World bronze medalist Svetlana Ankicheva of Kazakhstan 3-0, 2-0.

Doi, a California native, becomes the second U.S. wrestler to win a Cadet World title this year, joining Zain Retherford, who claimed a gold medal on Wednesday in men's freestyle at 63 kilos.

Doi, a Pan American Cadet gold medalist, was dominant through the tournament. She won her first match 4-0, 2-1 over Maria Marinska of Bulgaria. She followed that up with a pin over Sahilia Alakbarova of Azerbaijan. She then shut out Ankicheva in the gold-medal match.

Another U.S. wrestler, Kayla Miracle, reached the gold-medal match at 56 kilos on Thursday before falling to Japan's Ai Kuradate 3-5, 0-6. Miracle's road to the gold-medal match included a victory over 2011 Cadet World bronze medalist Ekaterina Myagkova of Russia in the semifinals.

Alyssa LaFrancis (65 kilos) placed fifth after losing in the bronze-medal match to Ragretta Ourbanzade of Azerbaijan 0-3, 0-5.

Julia Long (43 kilos) and Cadence Lee (49 kilos) also competed on Thursday for the U.S., but both failed to win a match.

Five more U.S. women's freestyle wrestlers will take to the mats on Friday, including Marina Doi's twin sister Regina at 40 kilos.
