Keiichiro Fukabori stormed to the top of the leaderboard after setting a course-record 10-under-par 62 in the second round of the ANA Open on Friday. Fukabori tore up Sapporo Golf Club's Wattsu Course in Hokkaido with eight birdies and an eagle on the par-5 12th to take a one-shot lead over South Korea's I.J. Chang, Shingo Katayama and Kiyoshi Murota on 10-under 134. Fukabori, who started the day in share of 62nd after Thursday's 72, bettered the course record of 63 set by Norio Suzuki in 1982. Masashi Ozaki equaled that record when he shot a 63 here in 1994. "It's the first time for me to shoot a 10-under in a tournament so obviously I'm delighted," said Fukabori, who claimed his eighth tour victory at last month's Sun Chlorella Classic. Fujisankei Classic runnerup Katayama, who has enjoyed top 10 finishes in his last four tournaments, went around the 7,063-yard layout bogey-free for the second day with six birdies in a 66, while Chang and Murota both shot 65s.
