The Mariners announced Tuesday that they’ve placed right-hander Kendall Graveman on the 10-day injured list due to neck spasms and selected the contract of right-hander Joey Gerber from their alternate training site. Seattle also recalled southpaw Taylor Guilbeau from its alternate site and optioned fellow lefty Zac Grotz. Graveman’s placement on the IL is retroactive to Aug. 3.

Graveman, 29, had a rocky debut effort with the Mariners on July 27 but looked sharper on Aug. 2 before departing the game with some discomfort in his neck. He signed a one-year deal with Seattle over the winter after missing most of the 2018 season and all of the 2019 campaign due to Tommy John surgery.

Before his injury, Graveman was a solid mid-rotation piece for the division-rival Athletics, who acquired him as part of their return in what ended up being a lopsided Josh Donaldson swap with the Jays.
