Dufner keeps calm and wins a major

Jason Dufner stayed as cool, calm and collected as one can be after winning his first career major. But that's just who he is, an athlete who plays with little emotion and plenty of skill. Although it was his skill that won Dufner the PGA Championship and has him the talk of the golf world, it was his tranquil demeanor that made him an Internet sensation. Move over Tewbowing and Kaepernicking ... Dufnering is the new fad.

Joining Dufner in the top five were Miguel Cabrera and Josh Reddick for their display of power at the plate, and Clayton Kershaw, whose MLB-low ERA dipped even further with a splendid performance on the mound. Usain Bolt nabbed a high ranking as he crossed the finish line first in the 100 meters at the World Track and Field Championships. Do you agree with our top 10?
