Hisashi Iwakuma, 36, a free agent who made only six starts because of shoulder problems, agreed to a minor league deal with the Mariners Monday.
The Mariners Monday signed RHP Hisashi Iwakuma to a minor league contract and invited the former starter to spring training. Iwakuma became a free agent after the World Series and will be attempting a comeback after spending most of the 2017 season on the disabled list.
Iwakuma, 36, went 0-2 with a 4.35 ERA with 16 strikeouts and 12 walks in six starts in 2017. He was placed on the 10-day DL with right shoulder inflammation May 10 (retroactive to May 7) before being transferred to the 60-day DL July 24. Iwakuma underwent arthroscopic debridement surgery Sept. 27.
In 2016, Iwakuma went 16-12 with a 4.12 ERA with 147 strikeouts and 46 walks in 33 starts. His 16 wins are a career high, and he led the club in wins (16), starts (33), innings (199) and strikeouts (147).
Among American League leaders since 2012, Iwakuma ranks fifth in walks per nine innings pitched, sixth in winning percentage (.618), eighth in ERA (3.42) and strikeout-to-walk ratio and ninth in wins (63).
The Tokyo native has spent his entire six-year MLB career with the Mariners, compiling a record of 63-39 with two saves and a 3.42 ERA with 714 strikeouts and 185 walks in 150 appearances. On Aug. 12, 2015 vs. Baltimore, Iwakuma tossed the fifth no-hitter in club history (fourth individual no-hitter).
