it certainly looks like Triple-A Norfolk right-hander Frank Mata will be one of the two players the Orioles add when they put relievers Koji Uehara and Alfredo Simon on the disabled list.
Mata was "unavailable" for Norfolk tonight in a save situation in the Tides' 2-1 victory. That's interesting because Mata is the Tides' closer, and the team's best reliever and he hadn't pitched in a couple of days. He's also not injured. All that probably means that he'll join the Orioles tomorrow, but perhaps I'm jumping to conclusions.
As for the other moves, we'll obviously know more tomorrow. If Jake Arrieta is scratched from his afternoon start for Norfolk or pulled after one or two innings, I think we can assume that he'll join the Orioles in time to make Saturday's start. That will also mean that David Hernandez is headed to the bullpen, where he could close before too long.
Fellow prospect Chris Tillman allowed one run over six innings tonight for the Tides, lowering his ERA to 3.12. Assuming the Orioles continue with their plan of inserting Hernandez in the bullpen, Tillman would be in line to start Saturday if Oriole officials deem him more ready for the assignment than Arrieta. It also helps that Tillman is on the 40-man roster.
But in probably wouldn't make sense to promote Tillman until Saturday. That still makes it likely that another reliever will join Mata on the way to Baltimore tomorrow. Could it be Alberto Castillo who could become the situational lefty with Ohman inheriting the closer role?
As I said, we'll know more tomorrow.
