CRACKER JACK
The RHHDAS has 1895 and Dickson's BASEBALL DICTIONARY (Which I'm late
submitting to--why isn't he online? Why did I have to introduce myself to
Christine Ammer the other day at ADS and tell her I've antedated hundreds of
her stuff?) has 1908!! "Cracker jack" wasn't rare in baseball; the term was
used before the food(?) product.
This is from the Kansas City Journal, 17 May 1888, pg. 2, col. 5:
The Derby was a fair race, but the Brooklyn handicap was a "Cracker
Jack."
This is from the New York Sporting Times, 11 July 1891, pg. 5, col. 2:
Shannon is putting up a beautiful game at second base. He is the
cracker-jack of the association, all points considered.
