On occasion, Davis Cup has served as a needed pick-me-up for a top player after a disappointing result at a Slam. In 1982, John McEnroe recovered from his five-set loss in the Wimbledon final to Jimmy Connors by flying to St. Louis and beating Mats Wilander in a six-hour Cup epic. Djokovic may have felt a similar desire this weekend, when he played Serbia’s first-round tie two weeks after losing early at the Australian Open. His opponent on Friday, Daniil Medvedev, is ranked just 63rd, but the Russian’s ultra-flat strokes can be tricky to handle, and Djokovic fell behind a set and 0-3 before coming back to win in four. We’ll see what, if anything, that does for Djokovic’s season individually, but it could be the start of something big for the Serbian Davis Cup team. Its next tie will be at home against Spain in April, and you have to believe Djokovic will make himself available for it.
Davis Cup can be a balm for champions, but it can be an icy shower for up-and-comers. Even Pete Sampras got one in his first final in 1991, when he lost two singles matches in the U.S.’ defeat to France. This weekend, 19-year-old Zverev and 20-year-old Khachanov were both beaten by DC veterans (Darcis and Troicki, respectively). But no player has ever had as disastrous an introduction to the competition as 17-year-old Denis Shapovalov. Playing in his first live rubber on Friday, he lost in straight sets to Dan Evans. He was well on his way to doing the same on Sunday, when he fell behind two sets and a break to Kyle Edmund in the fifth rubber. As bad as that was for Shapovalov, though, things were about to get much worse.
