I would give (and I did, by golly) sad face here.
Pannone didn't blow the socks off in his opening outing but, as we know, those first outings can have a lot of nerves and/or bad luck. He's been a clear breadwinner as the Sounds most consistent starter (especially at the Home ballpark where he's been fantastic) and I would love for him to stick and keep pushing while simultaneously possibly leading that starting group toward a Playoff push. I certainly wouldn't begrudge him if he latched on as a claim or a FA signee with a team he feels he has a better 2nd opportunity with (depending on the convo had when DFA'd, obviously). But, also, to your point about facing the Brewers: we both know he would likely go perform a line like 6 IP, 3 H, 6 K, 1 BB, 0 ER in a shutout. Ugh.
