Juan Ignacio Chela is retiring from professional tennis, leaving with six ATP singles titles and three in doubles - all on clay.
The 33-year-old Argentine has been hinting at retirement for weeks, and he announced it on his Twitter account.
Chela reached three Grand Slam quarter-finals - the French Open in 2004 and 2011, and the US Open in 2007.
Known as "El Flaco" (The Skinny One), Chela is retiring with his singles ranking at No 176 and career earnings at $6.5 million.
