ATP chief to stand down
The ATP have announced that executive chairman and president Brad Drewett is to stand down after being diagnosed with motor neurone disease.
The 54-year-old Australian took on the role as men's tennis supremo at the start of last year but will now enter a transition period until a successor is appointed.
"It has been a privilege to serve as executive chairman and president of the ATP, an organisation that I've been a part of for more than 35 years since I became a professional tennis player," said Drewett, who reached a career high of 34 in 1984.
"I hold the ATP very close to my heart, and it's with sadness that I make the decision to enter this transition period due to my ill-health."
World number two Roger Federer, the president of the ATP player council, said: "Brad has become a good friend of mine over the years and this is very sad news for all of us at the ATP and the entire tennis community.
"He is well liked and respected by everyone and has done a tremendous job in leading the ATP over the past 12 months, overseeing some major initiatives and a record-breaking year in 2012.
"His dedication and service to the sport over the years has been truly admirable and he has been a central figure in helping to grow the ATP product across the globe.
"Our thoughts are with him and his family during this difficult time."
