D-Backs catcher José Herrera went unclaimed on waivers and was assigned outright to Triple-A Reno, according to the MLB.com transaction log. Arizona designated him for assignment when Gabriel Moreno returned from the injured list last week.

Herrera has played parts of four seasons as a light-hitting backup. He’s worked behind Moreno for the past three of those. The switch-hitting Herrera has tallied 204 plate appearances this season. He has slashed .187/.285/.259 with a pair of home runs. He has hit a trio of homers among his 562 career trips to the dish.

The Diamondbacks valued Herrera’s glove and clubhouse presence enough to stick with him as a backup despite his lifetime .200/.280/.259 batting line. Veteran James McCann, signed when Moreno went on the IL in late June, has hit three homers with a .326 on-base percentage in 30 games. McCann figures to pair with Moreno for the final month of the season. Herrera will become a minor league free agent at the end of the regular season unless the D-Backs add him back to the MLB roster in the next few weeks.
