Don't think Fett has ever been the same since losing to Wozniacki from 5-1 up in the third in the Oz Open a couple of years ago.
Yep, that does seem an unfortunate big turning point for her in the wrong direction, match point(s) as well. It was going well for her, reached a WTA semi, into the top 100, and in that position against the recent WTA Finals champ, who obviously went on to win the AO (which probably worsened the blow), and not long after she's fallen to in and around the 200s. Still young though, so hopefully she can get back on track at some point, ideally after this little GB swing though .
