This happened a few nights ago.
In a match between the Washington Kastles and New York Sportimes, Paes hit a smash that nailed Robby Kendrick. The Sportimes coach then ran and got into Paes' face, as did Johnny Mac. Kendrick then hit a serve right at Paes, that nailed him. Then it got all snippy and what not.

NEW YORK -- World TeamTennis has suspended and fined New York Sportimes coach Chuck Adams after his team -- which features John McEnroe -- and the Washington Kastles got into heated arguments over players getting hit by shots.
The league barred Adams from leading New York against visiting Kansas City on Friday night for "violating the World TeamTennis Coaches' Code of Conduct."
Adams went onto Washington's side of the court to confront a Kastles player Thursday.
The league called this "the first punishment" for what happened between New York and Washington on Thursday. WTT said it "continues to investigate the incident to determine if there will be any additional punishments issued."
