David McKay, a right-handed pitcher, was designated
for the assignment on Thursday, according to the A.
Lefty Ken Waldichuk, who has just received his first formal promotion to the major leagues,
will take his spot on the 40-man roster. Cody Thomas, an outfielder,
was also brought back to Oakland from Triple-A Las Vegas.
In July, McKay, 27, was requesting an exemption from the Ray company.
With the A, his third major league team of the year,
he pitched for two and a third innings (Rays, Yankees).
