Rain caused second-round play at the 2013 AT&T National to be suspended with Roberto Castro and Jordan Spieth holding a share of the lead at seven under par.
Per Golf Channel's official Twitter account, play was halted for the remainder of the day because of inclement weather.
Here is a look at the leaderboard.

Play will resume on Saturday with players who haven't completed their second round finishing up before third-round play begins.
Castro and Spieth Strong Again on Friday
Castro was the leader after the first round, and he did enough to maintain a share of the lead through Friday. He followed up his opening round five-under 66 with a two-under 69.
Birdies on the eighth, ninth and 16th holes highlighted his day. This birdie on 16 culminated his best-played hole.
Spieth sits at seven under par with Castro after coming through with five birdies on the front nine. He can only hope to continue his torrid pace after a two-under 69 on Thursday.

David Lingmerth Came to Play
After a bogey-filled three-over 74 in the first round, Lingmerth made all the right moves on Friday. He gave no shots back to the course and sunk five birdies en route to a six-under 65.
At one point, Lingmerth birdied three-straight holes from 10-12. With his spectacular second-round performance, Lingmerth moved from 79th on the leaderboard to tied for seventh.
If he stays under par for the remainder of the tournament, he'll have an excellent chance to win.
K.J. Choi Birdie-less Day Causes Steep Decline
Thursday's one-under 70 was enough to keep Choi within striking distance after the first round, but the five-over 76 from Friday kills any realistic shot at contention.
Choi probably wishes the rain came before his round began. He dropped 72 spots as a result of Friday's struggles.
He bogeyed the second, third and 18th hole, while double-bogeying the 10th. The 43-year-old won the tournament in 2007, but without some sort of miracle, he won't be a factor over the weekend.
Other Players Who Will Be Heard From on Final Two Days
Which long shot has the best chance at winning the AT&T National?
Spieth and Lingmerth weren't the only players who managed stellar performances in the second round. Lee also shot a five-under 66 to finish just two strokes behind the leaders.
Were it not for slip-ups on the fifth and 18th holes, the 26-year-old South Korean could be tied atop the leaderboard.
Lee hasn't finished better than 49th in a tournament this year, so his biggest challenge will be staying under par the rest of the way to maintain a solid score.
Romero is another player who has struggled to compete for all four days of events this season. He does have a top 10 finish at the Puerto Rico Open in March to his credit, but he's been a non-factor otherwise.
He was playing very well when play was suspended on Friday. Through 13 holes he was already four under par with five birdies. If he can pick up where he left off before the rain came, he'll set himself up for contention on Saturday and Sunday.
