Brad Drewett, President of Men's Tennis Tour, Dies at 54 Brad Drewett, a former professional tennis player who became president of the ATP last year and won a greater share of Grand Slam tournament revenue for players, died on Friday at his home in Sydney, Australia. He was 54. The cause was amyotrophic lateral sclerosis, also known as Lou Gehrig's disease, the ATP announced on its Web site. Drewett's background as a top 40 singles and top 20 doubles player on the pro tennis tour helped him establish a rapport with current stars. "He had the courage to stand up and to try to change some things in our sport for the better," Novak Djokovic, the top-ranked ATP player, said this week. Drewett secured significant increases in prize money from all four Grand Slam events, especially Wimbledon, which announced this year that it would offer the largest purse in tennis history. Losers in the first three rounds of the tournament will earn 60 percent more prize money than in 2012. Bradley Dara Drewett was born on July 19, 1958, in Maclean, Australia. He competed professionally from 1976 until 1990; won two singles titles and seven doubles titles; and ended his career with a 181-226 record. After he stopped playing, Drewett became a tennis commentator on Australian television and worked for the ATP in various capacities. He was named president in January 2012. Survivors include his wife, Joanne; three sons, Jackson, Joe and Tom; and a daughter, Ally. The ATP has not yet named a new president.
