tennis interruptus
The letdown felt by an avid tennis fan after spending two weeks watching one of the big, televised tennis Grand Slam tournaments, such as Wimbledon, the French Open, the U.S. Open, or the Australian, after the last match (usually the men's singles finals) is done as there are no more to look forward to and schedule around for a while.
Many of us who watched the 2011 U.S. Open men's singles tennis final match between Novak Djokovic and Rafael Nadal knew it was not only an incredible match marking the end of the two-week build-up and anticipation of the next match (aka battle of the Titans) to come--it was also the beginning of the "tennis interruptus" letdown until the next Grand Slam Championship.
