Juan Martin del Potro’s Twitter has been silent for the past few months (apparently he has better things to do), but a decent percentage of his most recent Twittering concerns his love of timepieces. In particular, he loves the idea of a digital clock that sticks out and pokes you if you touch it. If he wins today’s match, he needs to make sure that he doesn’t miss the final due to injury from slapping the snooze button.
