SEATTLE (AP) The Seattle Mariners will have right-hander Hisashi Iwakuma under contract for the 2015 season.
The Mariners announced Thursday that Iwakuma's $7 million option was vested based on his on-field performance. Iwakuma missed the first month of the 2014 season but went 15-9 with a 3.52 ERA in 28 starts. In 91 career games with Seattle, Iwakuma is 38-20 with a 3.07 ERA.
General manager Jack Zduriencik said at the end of the season that Iwakuma would be returning for 2015.
