American journeyman Christian Pena set himself up for a first career victory on the Japanese tour Saturday, shooting a third-round 66 that gave him a two-stroke lead at the Sun Chlorella Classic.

Pena, who has gone 54 holes without a bogey, followed his consecutive 67s with another fine display of his all-around game as he moved to 16-under-par 200.

Naomichi Ozaki shot a 68 and remains in a tie for second at 14-under 202, joining overnight leader Hideki Kase who had a 69.

Tsuneyuki Nakajima, who won the Diamond Cup for his first victory in seven years, is a further stroke behind after a 67.

Yasuharu Imano, winner of the previous two tour events, matched the day's low round with a 64 and pulled within five shots of the lead in his bid to tie the tour record for consecutive victories.

Pena joined the Japanese tour after playing on the Canadian and Asian circuits.
