Phil Mickelson will complete a career grand slam of Majors if he wins at Torrey Pines, but McGinley cannot see the 51-year-old challenging again on a course that will not suit his brand of golf.
"Phil doesn't have a great record around Torrey Pines and there is a reason for that," stated Sky Sport analyst McGinley.
"I know he has lived in San Diego most of his life, and he is familiar with the test, but he is 51 years of age and this course is not suited to his game.
"I'd say there's been a lot of energy drained from him the last two or three weeks with the excitement of everything that's gone on, but it will be very different this week.
"It wasn't crazy to see Phil winning around Kiawah Island. It wasn't crazy to see Padraig performing well around Kiawah Island because that was the exam. It was a test of guile and those two guys have that in abundance.
"Experience was a big thing, the short game was a big thing. This is a very different test to Kiawah Island, and I am really expecting to see one of the top players in the world come to the fore this week, particularly the bigger hitters at the top of the world rankings.
"It's horses for courses and Torrey Pines will play into the hands of the big hitters. I see one of the big names in the top ten coming through and winning with powerful hitting, power out of the rough and getting the job done on the final Sunday."
