The Mariners on Saturday optioned left-handed pitcher Ariel Miranda to Class AAA Tacoma following a shaky performance Friday night that typified an underwhelming spring for the 28-year-old.
Miranda allowed four runs on five hits with two walks and two strikeouts in four innings a 4-0 split-squad loss to the Angels Friday, a game in which Seattle did not get a hit. Miranda gave up two runs each in the second and third innings as his spring earned run average rose to 6.14.
He had allowed 10 earned runs in his last 8.2 innings in his last three starts.
