SPRINGFIELD, N.J. (AP) — The weather matched the mood of Dustin Johnson and others trying to make up ground Friday in the PGA Championship.

Jimmy Walker took a one-shot lead into the second round at Baltusrol and did not play until the afternoon. Johnson was the biggest surprise of the opening round when the U.S. Open champion had a pair of double bogeys and only one birdie on his way to a 77.

He stood outside the clubhouse as a steady rain fell, knowing he had to make up ground to avoid missing his first cut in nearly 18 months on the PGA Tour.

Two-time major winner Martin Kaymer was one shot behind, and British Open champion Henrik Stenson was two shots back. Both played in the morning.
