Bob Bryan

Bob Bryan, the left-handed half of the Bryan twins, gave the most successful men's team of the Open era its big serve and forehand power from the ad court. With his brother Mike he won 16 Grand Slam men's doubles titles and Olympic gold in London in 2012, and their chest bump after big points became doubles' best-known celebration. A lefty-righty pairing like theirs puts forehands on both outside lanes.
