I think public televising of Gulbis new forehand should be prefaced with a "do not try this at home!" warning.
I would love to hear how he dreamed up this monstrosity and then sell it as thinly veiled Fear and Loathing in Las Vegas sequel.
He is playing better, but the difference, as it always was, is between his ears.
