Agassi vows to carry on playing
From BBC Sport website:
Andre Agassi has put his retirement on hold for at least another year as he prepares to return to action at the Masters Cup in Shanghai on Monday.
Agassi last played in his US Open final defeat to Roger Federer in September and says that loss has inspired him to continue to challenge for titles.
"I want another chance, that's the way it is," said the 35-year-old American.
"It brings out my motivation to do things I don't even think I'm capable of doing."
Agassi will make his comeback against Russia's Nikolay Davydenko on Monday and is the oldest player by eight years at the season finale.
The third seed, whose lay-off has been tailored to get him fit for Shanghai, added: "I want to keep doing this so I have to choose my poison. "Not playing is not always easy and it's not always a great decision in the short-term but my intention is to do this for another year."
