The Mariners will activate starter Hisashi Iwakuma from the 15-day disabled list on Monday and have optioned outfielder James Jones to Triple-A Tacoma to create roster space, Bob Dutton of the Tacoma News Tribune reports.
Iwakuma has been sidelined since April 21 due to a strained lat. The 34-year-old right-hander had compiled a 6.61 ERA with an 11/3 K/BB ratio in 16 1/3 innings prior to the injury.
Iwakuma may be auditioning for prospective teams as he can become a free agent at the end of the season. He’s served as a quality starter for the Mariners between 2012-14, with a 3.07 ERA over 524 innings.
