Martinez was outrighted to Triple-A Oklahoma City on Tuesday, MLB.com reports.
A left oblique strain delayed Martinez's 2013 debut, which took place on April 21. He racked up 33 at-bats over 11 appearances until he was designated for assignment last Monday, posting an unimposing .182/.229/.273 slash line. In the meantime, he'll continue to provide organizational depth in the outfield.
