Did you mean to say Casas won't be ready until next year?
German has been more than okay. His .490 OPS Against is off the charts good.
Bello, Murphy and Walter all took steps up, while Groome and Gonzalez maybe stayed even. Walter still has an insane K:BB ratio of 75:7 in under 58 IP!
Wink & Seabold have both done about as well as you can do at AAA. Now, we await their MLB fate.
I was never that high on Downs, so I wasn't shocked.
I would not say Mayer has been "pedestrian." He's at .820 after his first 156 ABs. He's got a .352 OBP and 9 SB (0 CS) in just 38 games.
Yorke has been a let down, so far, yes.
Rafaela will jump many slots on the mid season ranking lists.
Kavadas and Hickey look like gems. Jordan has stepped it up.
All-in-all, I'd say there has been more good than bad, but it's not a landslide.
