The A's recalled 1B/OF Matt Olson on Thursday, sending Cesar Valdez back down to Triple-A. Olson is expected to fill a backup outfielder role and is unlikely to make a fantasy impact. Once considered a promising prospect, Olson hit .095 (2-for-28) last season in the MLB and is now hitting .216 in Tr[...]

Steven Matz was finally called up. It was a little bit earlier than I had expected, but he made his MLB debut last Sunday. He threw quite well, but really dazzled with the bat, going 3-3 and driving n four runs. Did I ever mention that he can hit? Probably not.
