Watch: Spieth to caddie, 'What were we thinking, dude?'

Jordan Spieth and caddie Michael Greller have a unique work relationship.

However, like any employer/employee relationship, Greller is going to hear from his boss when he gives the wrong advice.

During the second round of The Players Championship on Friday, Greller got some feedback when Spieth's shot came up short from 119 yards out.

It's Spieth's first tournament since his Masters collapse last month.
