Taijuan Walker returned to the Mariners on the promise that he’d get a chance to be a starter and revitalize his reputation following 18 months of recovery from Tommy John surgery. The Mariners signed Walker with the goal of getting quality innings from a still-young player who could be a role model for their other young pitchers, an example to flex their player development muscle, and potentially a trade piece at the deadline. Today, as the Mariners traded Walker to the Toronto Blue Jays for a Player To Be Named Later, it seems as though all of those goals have been achieved to some degree.
