Nationals acquired RHP Omar Poveda from White Sox for cash considerations.

The 26-year-old hurler spent the 2013 season in the Braves organization, where he posted a 3.62 ERA, 1.30 WHIP and 133/59 K/BB ratio in 164 innings at Triple-A Gwinnett. He'll function as organizational depth for the Nationals.

Marlins outrighted RHP Omar Poveda to Double-A Jacksonville.

The move clears him from the 40-man roster. Poveda, 24, returned from Tommy John surgery last season and has a 4.34 ERA in four starts with Jacksonville this year. Baseball America didn't include him among the organization's Top 30 prospects.

Marlins optioned RHP Omar Poveda to Triple-A New Orleans.

Povedo returned from Tommy John surgery last season and posted a 4.32 ERA and 116/54 K/BB ratio over 156 1/3 innings with Double-A Jacksonville. Baseball America didn't include the 24-year-old right-hander among the organization's Top 30 prospects.

Marlins acquired RHP Omar Poveda and RHP Evan Reed from the Rangers for infielder Jorge Cantu.

Poveda, 23 in September, has not thrown a pitch this season because he is still recovering from Tommy John reconstructive elbow surgery. He had a 4.14 ERA, a 1.39 WHIP and a 73/48 K/BB ratio in 130-plus innings at Double-A Frisco in 2009. Maybe recovering from the elbow surgery will help him develop better velocity and control as it has other young pitchers.

Rangers transferred RHP Omar Poveda from the 15-day to the 60-day diabled list.

The move opens up a 40-man roster spot for Justin Smoak. Poveda is out for the year after Tommy John surgery.
