I didn't think this article alone was worthy of a FanPost, and I don't think there are enough DLDs, so I'll combine the two.
Keith Law (subscription required) had this to say about a few of the A's he watched:
Joey Devine hasn't appeared in a big league game since the end of 2008, missing two years due to Tommy John surgery, and his appearance on Monday made it look like he's a long way from getting back.
DLS - I do think he has promise as a reliever, but he could easily be Jesus Colome, tantalizing with plus stuff but never commanding it enough to be an elite closer or setup guy.
Grant Green - Shortstop can't be his long-term position, and I'd really like to see him in centerfield where his speed will play up while his inadequacies in the infield won't be such a problem.
I didn't copy and paste much of what he wrote, so I hope I'm not breaking any rules.
This is from a week ago, but Tollefson was outrighted to AAA. I guess that means Pennington will be back.
