The Mariners made some roster moves with a week remaining in spring training.
They optioned 23-year-old pitching prospect Rob Whalen to Triple-A Tacoma prior to their 8-4 loss to the Angels on Monday.
That was expected. Whalen was on the Mariners’ 40-man roster, but he’ll provide pitching depth in Tacoma.
He was leading all Mariners pitchers this spring with 21 strikeouts in 15 innings, though he was roughed up in his last start, allowing eight earned runs and he didn’t get out of the third inning in a 16-3 loss to the Indians.
