-29 Dustin Johnson [-9, -4, -4, -12]
-34 Justin Rose [-14, +5, -11, -14]
-35 Jason Day [-1, E, -14, -20]
-54 Jordan Spieth [-18, -5, -14, -17]
Day didn't really contend at The Masters, Rose not at the U.S. Open, otherwise they were all in the hunt for all four ... if you count losing by 20 shots over four tournaments as "in the hunt".
Zach Johnson missed the cut at the PGA, and due to a poor U.S. Open, was only -8 for the other three majors ... but he has one more trophy this year than Dustin or Justin.
