Chipper Jones made his 2012 season debut on Tuesday night against the Astros, hitting a home run as the Braves notched their first win of the year. "I think today he won our game singlehandedly, really," manager Fredi Gonzalez said of Jones, who also had a single. Jones missed Atlanta's first four games following surgery on March 26 to repair a torn meniscus in his left knee. He plans to retire at the end of the season. "I'm not going to say I was the spark," Jones said. "Obviously, the two-run homer was a big lift, but I'd much rather be a calming influence, have them look down there, see me and know that I'm going to put up some good at-bats and hopefully make the play when it's hit to me. And if they feed off that, great."
