Fredi Gonzalez is worried about the new Twitter account of Braves third baseman Chipper Jones. The Braves manager says his mood turned sour after reading the latest tweet on Chipper's @RealCJ10 feed: "Wow Mikey Minor! Hats off to Blanton too. They were dealing. 4 game streak since I got on the twitta. Got a date wit the Doc tmrw. Go Bravos." Gonzalez said Sunday he "tossed and turned all night" as he worried about Jones' chronic knee problems. The manager finally realized Jones was referring to Phillies ace Roy "Doc" Halladay, who is starting against Jones and the Braves on Sunday.
