Novak Djokovic and Andy Murray are building a Grand Slam rivalry, one that perhaps someday will merit mention alongside Roger Federer vs. Rafael Nadal, or Djokovic vs. Nadal.
When the No. 1-ranked Djokovic faces No. 2 Murray to determine Wimbledon's champion Sunday, it will be their fourth meeting in a major final, third in less than a year.
Djokovic beat Murray at the Australian Open in 2011. Murray beat Djokovic at the U.S. Open last September. Djokovic beat Murray at the Australian Open this January.
That's not yet quite up to the lofty standard set by Federer and Nadal, who played each other in eight Grand Slam title matches from 2006-11. Djokovic and Nadal have contested five major finals since 2010, including a stretch of four in a row.
