Sampras held at least one Grand Slam in the previous 4 from 1993 Wimbledon to 2001 Wimbledon, until Federer beat him in the 4th Round. Sampras would win just one more Grand Slam.

Federer held at least one Grand Slam in the previous 4 from 2003 Wimbledon to 2011 Australian Open, until Djokovic beat him in the semifinals. Federer would win just one more Grand Slam.

Nadal held at least one Grand Slam in the previous 4 from 2005 French Open to 2010 Australian Open, until Murray beat him in the quarterfinals. Nadal would win three consecutive Grand Slams. Nadal held at least one Grand Slam in the previous 4 from 2010 French Open to 2015 French Open until Djokovic beat him in the quarterfinals. How many more Grand Slam wins await Nadal?
