AT 7:45 today, Andy Murray will face Roger Federer. Murray weighs just a kilogram less than Roger, but is actually 2 inches taller. But, Federer has won 875 matches in his career, whereas Murray has won only 377. However, experience is thrown out the window between these two , as the Scotsman leads their head-to-head 10/8. The last two of these were in Shanghai and at the Olympics, but Federer won the three before that. Still though, the only times Murray has met Federer in the World Tour Finals, the continental Eupropean – Roger – has won every time! They were both in round-robin situations though, and their other matches suggest that maybe 25 year-old Murray performs better under pressure.
