It was a tough day for New York Yankees’ farmhands over at the Blue Jays’ minor-league complex on Tuesday as the Bombers’ Class-A youngsters had to face a trio of big-league starters: R.A. Dickey, Darren Oliver and Josh Johnson. Dickey, the Jays’ knuckleballing ace, drew a large crowd of spectators even as he threw his pre-game bullpen to catcher Henry Blanco. “That’s just nasty,” said one of the Jays’ minor-league pitchers as Dickey’s pitch dove sharply into the dirt before Blanco could snag it. “I’ve seen enough,” said another, a hitter, who seemed to be feeling sorry for his counterparts in the opposite dugout. Recently returned from pitching in the World Baseball Classic, Dickey threw two innings in the Class-A minor-league game, giving up one hit. He could have simply thrown a regular bullpen session, but prefers facing live hitters and simulating game situations. “I enjoy in my mind working Michael Bourn well before I see him,” Dickey said, referencing Cleveland’s leadoff hitter and the first batter he is likely to face on opening day.
