Former top 10 ATPer Felix Mantilla announced his retirement from professional tennis a year after his return (he took a break after successfully recovering from skin cancer).
The most prestigious of his 10 singles titles — all on clay — came at the 2003 Masters Series tournament in Rome.
We’ll miss your neck flap caps, Felix! And everyone, remember: don’t get stingy with your sunblock.
