Late triple bogey forces Korean to share lead with ill Kuchar

LEMONT (Illinois): Charlie Wi carded a two-under 69 to share the BMW Championship second round lead with Matt Kuchar on Friday but squandered a chance to have the top of the leaderboard to himself with a late triple-bogey.

Cruising through an unblemished back nine with three birdies, the South Korean’s round went from brilliant to ordinary in a hurry with the seven at the par-four 16th.
