Call this a Serena incident (before there was a Serena incident). From the book ON THIS DAY IN TENNIS HISTORY ($19.95, New Chapter Press, www.TennisHistoryBook.com), it was on Oct. 4, 2007 that Stefan Koubek used “strong language” to challenge officials and was disqualified from his second-round match at the Metz Open in France. The book excerpt that describes the incident is excerpted below.
2007 – Austrian Stefan Koubek is disqualified from his second-round match with Sebastien Grosjean at the Metz Open in France when he uses inappropriate language in an argument with tournament referee Thomas Karlberg. With Koubek leading 5-7, 7-6, 4-2, the Australian left-hander argues with Karlberg over the ruling to replay a point due to a linesperson being unsighted and missing a call. Says Karlberg, “On the first point of the seventh game, on Grosjean’s serve, a Koubek forehand close to the baseline gave a 0-15 advantage to Koubek, but the umpire realized Grosjean was in the way of the line judge, who was therefore unable to judge the point. In this case, the rule is to replay the point. Koubek disagreed and asked for the supervisor’s intervention. He did not want to accept the rules and used strong language. I told him the match was over and asked the umpire to announce it.”
