Buck Showalter used Wednesday to give some work to his best bullpen arms. Luis Ayala, Darren O’Day and Jim Johnson faced hitters for the first time this spring in the Orioles’ 19-7 rout of Spain’s team in the World Baseball Classic at Ed Smith Stadium. Spain has just two players on major league 40-man rosters, and they were clearly overmatched against the Orioles Jake Arrieta and Zach Britton were both given work. Arrieta allowed an unearned run in three innings. Britton, who is jockeying with Arrieta, Steve Johnson and Jair Jurrjens for the fifth starter job, gave up three runs and four hits in two innings. “They feel good physically, and that's good enough for me right now," Showalter said. Arrieta had no idea who he was facing. “It doesn’t really matter, one way or the other,” Arrieta said. “It’s hard to know their strengths and weaknesses.” Johnson allowed an unearned run in the eighth inning, Ayala, no runs and two hits in the fourth inning and Darren O’Day two runs and three hits in one inning. “That was the whole idea, to get them out there,” Showalter said.
