Muto's 63 helps him win Dunlop Phoenix

Miyazaki, Japan – Toshinori Muto shot an eight-under 63 on Castano and win the rain-shortened Dunlop Phoenix by four strokes.

Muto finished 54 holes at 12-under 201 at Phoenix Country Club to post his fourth Japan Tour win and first since 2009. Fernandez-Castano, who blew a final-round lead last week before winning the Singapore Open in a playoff, shot an even-par 72 and finished second at eight-under.

Shane Lowry (68) and Ricky Barnes (68) shared third at minus-seven, while Brendan Jones (68) took fifth at six-under.

Fernandez-Castano had only one birdie on the day at the 11th, and by then it was likely too late. Muto birdied four of his first five holes and six of his first eight to take the lead.

Muto's only misstep came with a five-stroke lead on the 18th -- a bogey -- so he was in no danger of losing the tournament by that point.
