Parker is a former first-round pick who had 112 strikeouts in 130 2/3 innings last year at Double-A Mobile. Cowgill hit .354 with 30 stolen bases last year at Triple-A Reno. And Cook had a 2.21 ERA with 19 saves last year between Double-A Mobile and Triple-A Reno.
Parker will compete for a spot in the A’s rotation, Cook will compete for a spot in the bullpen, and Cowgill will be the leading contender for the A’s opening in center field.
