Wouldnt someone who was invincible win more than 2 slams, LOL! Yes of course Tracy was up with Chris and Martina for a period. However she still never ended a year ranked #1, and never reached a major final outside of hard courts or the U.S Open. The Martina of 80-81 was also nothing like the future beast Martina. As for Chris, Tracy is a bad matchup for her, so looks better in the matchup than she really is, similar to Sanchez Vicario when playing Graf, Hingis when playing Seles, and numerous other cases.
TMF on Jan. 2011- Serena is washed up for good, TMF in Oct. 2009- Nadal has won his final slam, TMF in 2011- Woz will beat Serena at U.S Open
