I must admit I would be very skeptical and leary of any trade including Diaz, but I'm just trying to prepare myself emotionally in case Dipoto does.
I thought I read somewhere that Dipoto was some how talking of still picking up Aoki's option even though it did not vest... but I'll admit I have no idea if that is legal or possible.
Lastly, if you want to read a good article(s) on the Mariner's current relief corp, Kate Preusser at Lookout Landing has a 2 parter called "Jerry's school for gifted". Just to whet your whistle, here are a couple stats she gives:
Dan Altavilla - MLB's 17th fastest slider - Also in top 30 MLB relievers with 25% K rate on his fastball.
Nick Vincent - MLB's BEST Whiff rate on fastballs at 37.17% - MLB's 10th best called strikes on slider.
