Ivo Karlovic and Andy Murray are battling in the first set of their Round of 16 match at Wimbledon. Karlovic unleashed a hellish serve down the middle that Murray couldn’t reach. It then nailed a ducking lineswoman in the head. The announcers had some fun with the shot, even going back for a replay from another angle a few minutes later. The lineswoman is expected to finish the match. That’s no small feat considering Karlovic has one of the fastest serves in the world. As recently as 2012, he was clocked at 156 miles per hour.
