Fish to miss Australian Open
Mardy Fish will not be able to take part in the 2013 Australian Open but has targeted a return to the sport by February.
The 30-year-old American has not played since before forced to withdraw from his fourth-round match against Roger Federer at the US Open in September after complaining of heart palpitations.
Fish had an operation in May to correct a form of arrhythmia in his heart, and plans to return to the ATP Tour in February at the SAP Open in San Jose, California.
"The good news is that Mardy's health is improving and he is back on the court slowing getting back into his regular workouts," said Fish's agent, John Tobias.
Fish, who began the year ranked eighth but is now 27th, remains the third-ranked American - behind John Isner and Sam Querrey.

Fish has been troubled by the problem since February when he complained of an irregular heartbeat before a Davis Cup match and the condition worsened in the following weeks. At the Sony Ericsson Open in Miami in March, he woke up with his heart beating three times faster than normal.
Meanwhile, Robin Soderling is determined to return to the ATP tour even though he has not played a competitive match for 18 months after being diagnosed with the viral infection mononucleosis.
The two-time French Open finalist admits he has suffered several setbacks in his bid to resume his tennis career, saying "I feel really good, then I start to practice, and then I think maybe in a couple of months I can come back and I really believe it. Then I do a bit too much and wake up one morning not feeling well again."
Federer is 9/2 to win the 2013 Australian Open while Andy Murray can be backed at 5/2 and Novak Djokovic at 1/1.
