How do we know that Andy Murray is completely bored out of his mind back home in London while recovering from the back injury that forced him to skip the French Open? He's so bored he's tweeting. A lot. At least by Murray's standards.
Heading into the French Open, Murray's total tweet count for 2013 was 10. Ten tweets over the last five months. And how many times has the 2012 U.S. Open champion tweeted over the last five days? Twelve. He watched the two most exciting matches so far (Venus Williams vs. Urszula Radwanska and Gael Monfils vs. Tomas Berdych), got lost down the YouTube rabbit hole and is turning his attention to any and all sporting events in an attempt to stay occupied.
You guys, Andy Murray misses tennis:
