Chris Tillman will make his season debut for the Orioles Wednesday against the Mariners.
Jake Arrieta will be pushed back a day to Thursday. “This is what I?ve worked all season for,” said Tillman. “I?ve gotten in a good routine and it’s working well. I?m real excited.” Tillman posted a 3.63 ERA and nice 92/30 K/BB ratio over 89 1/3 innings for Norfolk this season.
