The Atlanta Braves added first baseman Ernesto Mejia and right-handed pitcher Juan Jaime to their 40-man roster, which prevents either player from becoming a minor league free agent. Mejia was signed by the Braves originally out of Venezuela in 2002. He left for one season in 2010 to be in the Kansas City Royals system but was resigned in 2011.

In 2011 in Double-A Mississippi, Mejia hit .297 with a ,906 OPS (on-base plus slugging), 37 doubles, 26 home runs and 99 RBIs. This year, for Triple-A Gwinnett, he was named International League rookie of the year hitting .296 with an .849 OPS, 32 doubles, 24 home runs and 92 RBIs.

As for Jaime, he was originally considered a top prospect for the Washington Nationals before Tommy John surgery caused him to miss both 2010 and 2011. He began 2012 in the Arizona Diamondbacks system but the Braves signed him late last season and he made his debut for high-class Single-A Lynchburg as a closer, going 51 and one-third innings with a 3.16 ERA collecting 18 saves in 42 apperances.
