Good morning from the Fort, where the sun is shining in all its glory for the school vacationers who are down this week from the Commonwealth, and where a few fans might even know that nonroster invitee Mitch Maier, an outfielder by trade and an auditioning first baseman, once pitched against the Red Sox. “A moment I’ll never forget,’’ Maier said the other day, “even though it was as nerve-wracking [an experience] as I’ve ever had in this game.’’ You can look it up: July 26, 2011. Maier’s team, the Kansas City Royals, entered the eighth inning trailing the Sox by six runs, 13-7. Maier was on the bench when Ned Yost, the Royals’ manager, asked him to go to the bullpen to warm up. The last time Maier had pitched was as a child. Never at Novi High School in Michigan, never at the University of Toledo, never in pro ball. Coming to bat in the inning for the Red Sox: Dustin Pedroia, David Ortiz, Carl Crawford, and Jason Varitek. “I’m thinking, ‘Great, this may go from ugly to real ugly quick,’’ Maier said. “My bullpen coach (Steve Foster) actually tells me, ‘You know Pedroia needs a home run for the cycle. He is going to be trying to take you deep.’ “Great. Not that I’m already nervous. I probably threw 30 pitches warming up, Way too many. Couldn’t even lift my arm the next day.’’
