The Atlanta Braves made another move to bolster their shaky bullpen Thursday, signing left-hander reliever Will Smith to a three-year, $40 million contract. The 30-year-old Smith went 6-0 with a 2.76 ERA and a career-best 34 saves for the San Francisco Giants this past season. The NL East champion Braves were looking to upgrade the bullpen after going through several closers last season, including Luke Jackson, Shane Greene and Mark Melancon.
