As I watched yesterday's dramatic men's Wimbledon singles final -- won by Roger Federer over Andy Roddick 16-14 in the fifth set for Federer's record 15th Grand Slam singles title -- the key factor that stood out to me was Roddick's consistency in getting his first serves in. Roddick bested Federer in first-serve percentage, 70-64, which contributed to Federer's complete inability to break Roddick's serve -- until the very last game of the match. Some interesting serve-placement graphics are available here.
