Braves third baseman Chipper Jones could retire after next season if he has another frustrating campaign. He signed a three-year, $42-million contract extension in March that runs through 2012. "I'm not going to tolerate the numbers I have right now for very long," said Jones, who hit .110 with one homer in 22 games before Thursday, told the Atlanta Journal-Constitution. "I'm certainly not going to stick around for a big contract if I'm not having fun and not producing," added Jones. "I'm not saying I'm retiring at the end of this year or the end of next year, but if I become an average player, I'm not sticking around. "I'm not going to hamstring the ballclub with the money I'm making, and I'm not going to be happy being a mediocre player."
