Fourhand is the Daily Spin's occasional roundup of various hits and misses on tour.
MIAMI VEXED: Andy Murray was not happy when 1) a ball, apparently found in a flower bed from an earlier match, was used in his match against Denis Istomin, 2) that ball was weighted differently, as intended for WTA play and 3) chair umpire Mohamed Lahyani, in Murray's estimation, made him look like he was complaining for no reason in front of the Miami Open crowd. The Brit ultimately won the match, 6-3, 7-5.
SILVER BULLET: Funny person Sarah Silverman has joined the cast of the forthcoming “Battle of the Sexes” movie, set to star Emma Stone and Steve Carrell. The movie retells the story, of course, of Billie Jean King's legendary showdown against Bobby Riggs.
WEDDING BELLES?: Word is that the likes of Australian Open champ Angelique Kerber, Caroline Wozniacki and Sorana Cirstea will be guesting at Ana Ivanovic's wedding to soccer star Bastian Schweinsteiger, allegedly to transpire in June. Between that and Wimbledon, it will be a lot of immaculate white for Ivanovic in one month.
