Oakland A's acquire Cody Martin from Braves for international slot money, designate Nate Freiman for assignment

The Oakland Athletics have obtained right-handed pitcher Cody Martin from the Atlanta Braves for international bonus slot 53, which corresponds to the right to spend $388,400 on international signings without being subject to various penalties. Martin was optioned to Triple-A Nashville. To clear space on the 40-man roster, the A's designated right-handed batting first baseman Nate Freiman for assignment.

Martin, 25, has been starting for Atlanta's Triple-A club, making six starts out of seven appearances while striking out 33, walking nine, and allowing two home runs in 34⅓ innings, resulting in a 2.10 ERA. With the MLB club, Martin made 21 relief appearances, striking out 24, walking seven, and allowing four home runs in 21⅔ innings, resulting in a 5.40 ERA. Brooks Baseball records Martin as throwing a 91 mph fastball, slider, curve, sinker, and change.

Martin can conveniently slot in for Chris Bassitt's place in the Triple-A rotation while the A's figure out whether Sonny Gray can pitch Sunday after being released from the hospital for severe bacterial gastroenteritis.

Nate Freiman, 28, never advanced out of the 2013 rookie campaign where he batted .274/.327/.389 while locked into the active roster under Major League Rule 5, mostly against left-handed pitching. This year in the minors, Freiman is hitting just .171/.224/.188 with Triple-A Nashville in 129 plate appearances over 35 games.

Here's the new 40-man trade tree, with Martin replacing Freiman:
