I don't think Martina's talking retirement but the media and the fans are. I havn't read Martina's interview but reading all the articles written it sounds more like the media asked if she's rethinking her retirement and are writing it that way and she answered more like someone who was not going to decide after one loss and is looking and what she needs to work on. I'm sure Martina can see and will be told that what she has achieved so far is pretty amazing.
This is basically what I've read so far and it seems like everyone's over reacting.
Left to rethink the future of her second-winded career choice after making a celebrated return to tour play in January, the eighth-seeded Swiss was non-committal following the match, waiting for a more lucid moment before making a decision on her future.
“This is probably not the best day to ask,” said Hingis, the 1997 US Open women’s champion, after suffering her earliest exit ever in New York, dropping her career record in New York to 41-8.
“I mean, you can't just be down on yourself all the way because you lose a match here at the US Open. I have my people around me, my support system, so we just definitely have to step back and see what we'll do in the next days, next weeks, and next months.”
