The Mariners just announced that they have signed Hisashi Iwakuma to a minor league deal.

Iwakuma became a free agent earlier this month after the Mariners, not surprisingly, declined his $10 million option for 2018 after he made only six starts in 2017, posting a 4.35 ERA, 3.5 BB/9 and 4.6 SO/9 over 31 innings.
