I am not even going to entertain the idea of the Mariners signing Shohei Ohtani, I just don't think that is something they are going to entertain and it would probably take up all of the budget for their off-season. The Mariners have more holes to fill and adding Ohtani isn't going to make the Mariners a World Series team, they need more than that.
So in this article I am going to look at guys that I have seen that are available in free agency and via trade that the Mariners have been linked to.
Sign Yoshinobu Yamamoto for 9YR/$200M
Yamamoto is the best player coming out of the NPB league in Japan and is now able to negotiate with MLB teams. Yamamoto is only 25 years old and has already won 3 Cy Young equivalent awards in the NPB. In his seven seasons in Japan, he has a 1.72 ERA, a .915 WHIP, a 9.2 SO/9, and 2 BB/9. He is someone who has been an inning eater in Japan, pitching an average of 185 innings a season over the last three seasons. That is good for roughly 7 1/3 innings per a start. Yamamoto is someone I favor over Snell because he is younger, pitches deeper into games, and doesn't walk people at the rate Snell does.
