...and has always been that way.
When Jordan Zim pitched his no-hitter, the Post mentioned that the last pitcher to throw a no-hitter for a Washington ball-club was a young guy named Bobby Burke. Threw a no-hitter about 1931, when he was 24. Manager Walter Johnson praised Burke's "stuff", and the team kept hoping he would become an ace. Later, Bucky Harris called Burke, "The kid that had an eleven year tryout".
