The scene was all set for teen phenom Ryo Ishikawa to mark the week of his 19th birthday with victory at the tournament of one of his main sponsors.
Only rival Yuta Ikeda turned up to gate-crash the party.
Ikeda held on to his overnight lead to capture his second win of the season at the ANA Open on Sunday, firing a 5-under 67 to finish one stroke ahead of South Korean Kim Do Hoon (63) and American Jay Choi (66) at 14-under 274.
