Hisashi Iwakuma surpassed 162 innings last week, meaning he crossed the minimum innings threshold for his 2017 club option to vest at $14 million.

However, Iwakuma's contract also stipulates that he must finish the season without incurring a specific injury. While it seems likely the option will vest, his 2017 salary isn't yet guaranteed.

Iwakuma signed a one-year, $12 million deal with the Seattle Mariners (including a pair of vesting options) after a three-year, $45 million deal with the Los Angeles Dodgers broke down over health concerns.
