My "Mike Piazza on the 60-day DL" guess ended up closest, but it turns out it's Chris Snelling going to the 60-day, which shouldn't have been a surprise to me.

Also, Ruddy Lugo got sent down to the minors, mainly because he sucks. It's not clear to me why the A's are even bothering to hold on to him in the minors. Maybe they think there's something there they can fix?
