Umps don't matter. The O's have proven in this second game why they're not as good as the Yankees. Chen lays another egg, they load the bases with no outs in THREE innings and get a total of 3 runs out of it, and Arrieta continues his Jekyll and Hyde routine. Coming in with the bases loaded in the 6th and striking out the side, loading the bases himself in the 7th, getting two big outs, then serving up a grand slam to JP on a silver platter.
At this point, I have NO CLUE who I'd want on the mound for the O's in a WC game. I'd have to go with Tillman. Hopefully the O's are saving Hammel and getting him to 100% in case they need him for that one game playoff. At this rate, I'd take Bundy over Chen, Arrieta or Wolf.
