This A’s road trip will be a significant one for Chad Pinder, who next week will be making his first-ever appearance at Camden Yards as a big-league player. Pinder grew up an Orioles fan in Poquoson, Va. His father, Chris, played in Baltimore’s system and Pinder got his first taste of the majors when they’d visit the Orioles’ clubhouse and dugout to see Chris Pinder’s former minor-league trainer.
