R.A. Dickey may not start the All-Star Game, but the 37-year-old knuckleballer will appear on “Late Show with David Letterman” next Wednesday, according to two people familiar with his schedule.
This year alone, Dickey has scaled a mountain, written a book and become baseball’s best starting pitcher.
He enters Thursday night's start with a 12-1 record and 2.15 ERA.
