The A’s used the Sept. 1 expansion of roster limits mostly to augment the bullpen, four of the eight players promoted being right-handed relievers – R.J. Alvarez, Arnold Leon, Dan Otero and Ryan Dull.
Also called up one other right-handed pitcher, Cody Martin, who will be Tuesday’s starting pitcher against the Angels.
The A’s added one catcher, Carson Blair, one infielder, Tyler Ladendorf, and one outfielder, Jason Pridie.
To clear space on the 40-man roster for Blair and Dull, who weren’t on the 40, the A’s moved pitchers A.J. Griffin and Jesse Hahn on the 60-day disabled list, which doesn’t count against the 40-man roster, and Angel Castro was outrighted to Nashville.
