Rory McIroy isn't having the best year, season, or week. Ever since his new endorsement deal with Nike was announced in a laser light show in Abu Dhabi back in January, last year's world No. 1 has struggled to make much of a "dent" in any tournament or contend.

His season struggles have continued at Merion, where he's been out-of-form off the tee, with his irons, and around the green and is currently at 13-over.
