Mariners optioned RHP Shawn Kelley to Triple-A Tacoma. Kelley gave up a go-ahead two-run homer to Yoenis Cespedes in his lone appearance in last week's Opening Series against the A's in Japan. This move is a minor surprise, as the 27-year-old right-hander is expected to serve in a set-up role this season, but the M's sent him down because he had options remaining. He should be back before long.
