Walker has been the Mariners' consensus top prospect for the last two seasons and was recently called up after recovering from a shoulder injury he suffered in spring training and re-aggravated at the start of the season. He made two starts since being recalled on June 30, throwing 10 innings and giving up four runs. He had some control issues, however, allowing seven walks versus nine strikeouts.
Fellow pitching prospect, James Paxton, is recovering from a upper-arm stiffness and is expected back near the end of July.
Pryor has dealt with his fair share of injuries, but is healthy now and being called up. Mariners reporters speculated on Twitter that the roster move sets up a bullpen day for the big league club on Thursday, while allowing Walker to get his normal work in over the All-Star break.
Mariners can move Kuma to Saturday and start Young on Sunday while Walker can stay on normal rest with Tacoma — Ryan Divish (@RyanDivish) July 9, 2014
So, most likely bullpen, Felix, Iwakuma, Young to close 1st half while Walker gets work in Tacoma. Will learn more at 3:15. — Shannon Drayer (@shannondrayer) July 9, 2014
