MELBOURNE, Australia – The start of Ekaterina Makarova's fourth-round match against Kim Clijsters at the Australian Open was delayed slightly when the chair umpire noticed that a sponsor logo on the front of the Russian's shirt was too large.
The umpire, Mariana Alves of Portugal, asked Makarova to change the shirt before the match could begin. The player left the arena and returned without one of the logos on her shirt.
The Grand Slam Rule Book specifies that advertising logos cannot exceed four square inches (26 square centimeters) if there is one logo, or 2 two square inches (13 square centimeters) if there are two, on the front of a shirt.
Makarova later moved the logo from the front of her shirt to her right sleeve, where larger logos are permitted.
