While I think it's very unlikely for the O's to make the playoffs, I think it would be a lukewarm message to the fans if somehow the O's make the playoffs and Henderson is not available for the postseason roster. Especially if he lights it up immediately. With the Orioles selling at the deadline, they're showing a willingness to use their prospects as ammunition. If they're going to call up Gunnar, it doesn't make sense to not do it this week for a number of reasons.
