Six months after taking himself out of competition at the U.S. Open, American Mardy Fish has returned to action.

Fish has been dealing with an accelerated heartbeat and as a precaution, did not finish the last major of 2012, but he is back in a star studded bracket at Indian Wells, this week.

Fish defeated American qualifier Bobby Reynolds in the second round after receiving a bye in the first. He advanced in a 6-3, 3-6, 6-4 effort.

On his return, Fish stated, “This is the one that I was sort of targeting to hopefully come back for (Indian Wells). I sort of kept pushing back, and back, and back. And here we are. So it’s obviously nice to play. I’m fighting a lot of demons in my head at this point, but it’s nice just to play.”

Fish is the 32nd seed in the Masters 1000 event, the BNP Paribas Open.

Fish moves on to face Jo-Wilfred Tsonga, who is seeded 8th in the event, next.

Indian Wells has drawn a top fight group of players including, Novak Djokovic, Andy Murray, Roger Federer, Rafael Nadal, Tomas Berdych and others. It resembles a condensed bracket you would see at a Major.

Fish had contemplated retirement after the U.S. Open saying, “For the first three months after the U.S. Open, I had retired and non retired in my head almost every week ,and there was a while where I was done. I had gotten it through my head that I was done, when I was just trying to get my normal life back.”

It is good seeing Fish back. Whether he can get back to top American on tour, remains to be seen. And more importantly, whether his health allows him to continue.
