Mariners' Jhonathan Diaz: Sent down to minors

The Mariners optioned Diaz to Triple-A Tacoma on Wednesday.

Diaz made a spot start in Tuesday's 4-3 loss to the White Sox in place of the injured Bryan Woo (arm), allowing three runs over 5.1 innings in a no-decision. Woo's status remains in limbo, and Diaz could be considered for a call-up if Woo ends up landing on the injured list before his next turn through the rotation comes up.
