Athletics' Austin Pruitt: Operating as opener

Pruitt will operate as the Athletics' opening pitcher Saturday versus Houston, Martin Gallegos of MLB.com reports.

Pruitt will draw another start after serving as the opener Wednesday against the Mariners, tossing a scoreless first inning while allowing two hits. Hogan Harris was called up from Triple-A Las Vegas on Saturday and is expected to handle the bulk-relief role following Pruitt.
