Orioles manager Buck Showalter is not a guy who sleeps much regardless, but if there is something that is keeping him up at night, I'd have to imagine it is the Orioles' shaky middle-relief corps, the group that is supposed to get the ball and the lead to Jim Johnson, Koji Uehara and Kevin Gregg. Jason Berken was supposed to be the leader of that group, but he's now in Triple-A, stretching out to be a starter. The club doesn't trust Michael Gonzalez in clutch situations, and rightly so. Clay Rapada can't get righties out, so he's not a good option there. If Alfredo Simon is the team's long guy, that pretty much leaves Jeremy Accardo as the main option to get the ball to the back-end guys. Accardo has had some decent outings, and his 1 2/3 scoreless innings last night were instrumental in the comeback. However, it always seems that he's walking the tightrope and one pitch away from allowing the game to be blown open. Perhaps this is why: In 21 2/3 innings, Accardo has surrendered 25 hits, walked 14 and hit one. He has gotten out of several jams, but the nearly two base runners per inning don't bode well. This is where Simon could play a key role. If he's able to pitch that sixth and seventh inning on occasion and give the Orioles another reliable arm to serve as a bridge to the back end, that would be huge. The Orioles have plenty of other long men candidates. Either Brad Bergesen or Chris Tillman could do that job if they lose their rotation spot to Brian Matusz. Berken could do that as well after he gets stretched out. Mark Hendrickson is in Triple-A. But it's that "bridge guy" to help out Accardo who needs to emerge.
