Zach Johnson crosses Rae's Creek on No. 13 during the second round of the 2014 Masters Tournament at Augusta National Golf Club.

Zach Johnson suffered a penalty stroke that added to a rough two days for the former Masters champion.

Johnson’s ball moved while he addressed it on the sixth green, resulting in a one-stroke penalty. He took bogey on the par 3, one of three for Johnson on Friday, and shot even-par 72.

Johnson’s first-round 78 left the 2007 champion with a tough hill to climb to make the cut. He was unable to do so, finishing 6-over for the tournament.
