Unlike Giles, infielder Wes Helms (.232, four homers, 13 RBIs in 151 at-bats) doesn’t have minor-league options left, so the Braves couldn’t send him down without exposing him to waivers.
What they don’t realize is that (a) he wouldn’t be claimed, and (b) if he was, it wouldn’t be any loss. The story does more or less confirm that when DeRosa returns Garcia will get demoted. He doesn’t have any options either, but he also won’t be claimed, and if he were it wouldn’t be any loss. I don’t know why the Braves can’t see the parallel.
