Per a Braves press release:

The Atlanta Braves today claimed right-handed pitcher Cristhian Martinez off waivers from the Florida Marlins and optioned him to Triple-A Gwinnett.

Martinez, 28, pitched in 15 games (all in relief) for the Marlins last season and went 1-1 with a 5.13 ERA in 26. 1 innings pitched. After the 2009 All-Star break, he appeared in 10 games and posted a 3.86 ERA and a .224 opponents' batting average in 18.2 innings of work, with 11 strikeouts and six walks allowed.

The 6-foot-1, 185-pound Martinez went 9-3 with a 2.94 ERA in 17 games (16 starts) at Double-A Jacksonville last season. In seven career minor-league seasons he has 40-26 record and a 3.48 ERA in 112 games (104 starts), with 429 strikeouts and 123 walks in 607.2 innings pitched.

Look like another "live arm." The Braves use a 40-man roster spot on him, so I guess we'll compare him to Manny Acosta forever.

He's an interesting pitcher. I can't find him in any of my old Baseball America prospect handbooks. He used to be in the Tigers organization, during the same time as Jair Jurrjens and Brent Clevlen. We seem to be collecting a lot of ex-Tigers.
