Play has been suspended at The Barclays due to darkness with Tiger Woods at five-under through 13 holes in the first tournament of the FedEx Cup playoffs.
At one-under on his round, Tiger is five shots back of playing partner Kuchar, who is looking for his third victory of the year.
Woods will have a short look at birdie on the par-three 14th when play resumes tomorrow morning at Liberty National.
It was a relatively uneven day for Woods who started with three birdies in the first five holes and then suffered a trio of bogeys between the seventh and 11th holes to give it all back.
A birdie on the 13th gave the world No. 1 some momentum heading into an early Saturday conclusion to his second round.
