With Chris Davis taking a 25-game powder, the Orioles needed a corner infielder to help out. They just called one up: Christian Walker.
An interesting move, in part because they now will put Walker on the 40-man roster, starting his service clock. Also interesting because Walker himself could be an interesting player. A fourth round pick out of South Carolina a couple of years back, Walker has a lot of raw power — he’s hit 26 homers across two levels this summer — and can hit lefties, which may be pretty useful.
