I have to admit I didn't know they played together. I know about one time, I think it was in stanford a few years ago, and I know they won the tourny. did they play anywhere else?
Lindsay said once, in a chat that was done with her, that she loves playing with Martina, but that playing doubles with her as a regular thing is a bit strange with them both being each other's main competition. this was in the beggining of 2000, though, when just about every final was Marti v. Lindsay. things are different now, maybe it wouldn't be strange for them anymore.
