Matea is about to play her first event of 2014 this week in Sibenik, but will compete only in dobules partnering Martina Basic. Last year she has only entered 8 ITF doubles events, the last of which was in late May, and her last singles match happened 4 years ago (that same year she got her last singles win, coincidentally in Sibenik). Her win-loss record last year was 7-8, and she is currently outside of top 1000 in doubles.
I can't seem to find any info about what happened to her to miss out for all these years, guessing it could be something health-related, but it's such a shame for a solid player that she once was (a career-high ranking of 208 and 135, in singles and doubles respectively).
Hopefully she can at least have a few more good years on the Circuit as a doubles player exclusively, if that's what she's going for.
