The youngsters the Mariners are planning to play are primarily the position players, but we shouldn’t be surprised by a few on the pitching staff as well. The Mariners starting rotation coming back from the end of last season are Marco Gonzales, Yusei Kikuchi, and Justus Sheffield.
So the Mariners still have the fourth and fifth rotation spots to fill. Dipoto decided to go out and get a couple of veterans to fill those spots. He did so with pitchers who had injuries for the past couple years, figuring there was an upside for this coming season.
