Shingo Katayama shot a sizzling 7-under-par 65 to join Taiwan's Lin Keng-chi in a share of the lead after the second round of the ABC Championship on Friday. Looking to rebound after a disappointing showing at last week's Bridgestone Open, money rankings leader Katayama holed seven birdies in a blemish-free round at ABC Golf Club to hold a one-shot lead, with Lin on 9-under 135.
