He’ll ultimately be exposed to waivers, where other teams will have a chance to step into San Diego’s Rule 5 rights. If he clears, then he’ll be offered back to the Mariners.
Blash, 26, has only received 29 plate appearances on the year, but he’s largely been overmatched in his first run at the majors. The big outfielder has registered just three hits and four walks to go with 13 strikeouts.
San Diego surely always knew it was uncertain whether Blash would be able to stick at this point; after all, that’s why he was left off of the Seattle 40-man in the first place. He has shown some interesting skills in the minors, though. Last year, he ran up a composite .271/.370/.576 slash with 32 long balls in 476 plate appearances in the upper minors.
