Rodney, 41, pitched well for the Twins, racking up 25 saves with a 3.09 ERA with a 50/19 K/BB ratio in 43 2/3 innings. The veteran right-hander is owed the remainder of his $4.25 million salary for the 2018 season. His contract has a club option for next season worth $4.25 million with a $250,000 buyout.
Chalmers, 21, was selected by the Athletics in the third round of the 2015 draft. He was not rated among the Athletics’ top-30 prospects by MLB Pipeline. He has only pitched five innings this season with Single-A Beloit this season as he has been away from the team due to an undisclosed personal issue.
