A ruling on Serena Williams' US Open tirade is expected in the next two weeks.

"It's in the hands of the Grand Slam administrator, who I believe has now completed his investigation and will be making a ruling within the next two weeks," United States Tennis Association President Lucy Garvin told The Associated Press yesterday.

"That's what we have been told - that Serena would hear, we would hear."

The Grand Slam administrator is Bill Babcock.

Williams was fined $10,000 after her profanity-laced, finger-pointing outburst at a lineswoman during her semi-final loss to Kim Clijsters in September and she could face a much more severe penalty in the coming days.

"We really have not gone down that path of making a judgement as to what would be right or wrong at this point," Garvin said. "She was defaulted out of the singles and she has apologised sincerely. So we'll just have to see what the Grand Slam administrator comes to the Grand Slam committee chairs with. I think Serena is very anxious to hear."

Speaking ahead of the Fed Cup final between the United States and Italy, Garvin also said she has discussed Andre Agassi's recent drug revelations with some board members, but that "nothing official" has been decided.

"It definitely was surprising to all of us," Garvin said. "Andre is a very open individual now - he's older, he's matured, he's been a wonderful ambassador of the sport. I'm not sure of his reasoning as to why he felt he wanted to disclose that but that's his personal business and he chose to do it."

In his book Open, which goes on sale on Monday, the eight-time Grand Slam champion said he used crystal meth in 1997 and failed a drug test - a result he says was thrown out after he lied by saying he unwittingly took the substance.
