The Asian Poker Tour Championship (APTC) series in Taipei may be only a few days old, but it's already making waves in terms of massive fields and huge prizes, not to mention some new names on the freshly-designed winners’ trophies.

Ruiko Mamiya is one of those names, following victory in the TWD 15,000 (approx. USD $495) buy-in National Cup Championship. The former poker dealer from Japan overcame a record 2,398 entries — the largest side event field in APT history — to win the prestigious Pewter Lion trophy alongside a payout of TWD 3,087,700 (~USD $102K).

In doing so she also becomes only the third female winner of an APT marquee event, following APT Main Event winners Kitty Kuo and Dang Thi Hue, and the first female winner of an open event at the APTC.

Mamiya, who reached the final table of the $2,500 Limit O8 event at last summer’s WSOP, was the shortest of the final three stacks on Sunday when play was paused to discuss a deal. With a near-even chop agreed, she quickly turned the tide, eliminating her last two opponents to get her hands on the trophy and the slightly larger share of the prizepool.
