ARDMORE, Pa. -- Martin Laird was probably speaking for the field when he called the final five holes at Merion the "hardest finish in golf I've ever played."
The 18th has played as the toughest this week while No. 15 ranks third and the 14th is the fifth hardest. Nos. 16 and 17 are no slouches, either, clocking in at ninth and seventh, respectively.
Of the three players tied for the lead at 1 over right now, Phil Mickelson has had the most success on the finishing stretch. He has played the five in 1 under with a bogey and a birdie at No. 18 and Saturday's dramatic birdie at the 17th that gave him the overnight lead.
Rose, on the other hand, has had the most trouble with the final five. He was 6 over prior to Sunday and just added two more bogeys at Nos. 14 and 16.
Mahan is 4 over for the stretch with just one birdie to his credit. The 18th hole has been the most problematic for him with a double bogey in the first round and bogeys in the next two.
