Luke Hughes' stay with the A's did not pass the week mark, as the infielder was designated for assignment to make room on the roster for the newly acquired Brandon Inge.
Hughes, initially claimed off waivers from the Twins, compiled just one hit in 13 at-bats with the A's and was sidelined for two games because of flu-like symptoms.
"Unfortunately, he was up against some long odds, especially with the sickness he was dealing with," manager Bob Melvin said. "I think, more than anything, it was too bad the timing of his illness [that] he wasn't able to get in there on a consistent basis."
The A's have 10 days to trade Hughes, release him or pass him through waivers.
