The Braves agreed on Wednesday to trade Rafael Soriano to the Rays, a Major League source said. Pending medical evaluations, the deal could be announced as soon as Thursday. Before Soriano provided some surprise by accepting an arbitration offer on Monday, Wren envisioned receiving the 2010 First-Year Player Draft pick compensation that would come courtesy of the fact that the 29-year-old reliever was classified as a Type A free agent. Now, it appears that the Braves will have to settle for a reliever who could at least provide some organizational depth. Atlanta will receive Jesse Chavez, a 26-year-old right-handed pitcher who was acquired by Tampa Bay in an early-November trade that sent infielder Akinori Iwamura to Pittsburgh.
