Martinez (hand) underwent an MRI on Friday, which came back negative, Jack Magruder of FanRag Sports reports.
Although the hand contusion seemed like a minor injury for Martinez, these test results confirmed that he won't be out for long. He could make his return to the lineup for Saturday's game against the Nationals, but the Diamondbacks may choose be patient with their big-ticket acquisition's recovery. In Martinez's stead, Daniel Descalso earned a start in the outfield during Friday's series opener.
