(Reuters) - Seven months after his grand slam debut, journeyman Jason Jung recorded the biggest scalp of his career when he upset Frances Tiafoe 6-3 7-5 in the second round at the New York Open on Thursday.
After squandering a match point while receiving at 5-3, Jung was broken in the next game and the match seemed to be slipping from his grasp at the Nassau Coliseum on Long Island.
