M 6/23	Milwaukee	L 1-3	9	7	3	2	3	4	L 3-6	Duke returns after a suspension.  Co-owner Henry “Hy” Hach said, “Duke was not in condition to pitch ball, nor has he been for some time.”  There may have been other reasons, and one of new manager Tim Hurst’s first duties as manager was to get Duke into shape to pitch.  According to the Minneapolis Journal of Saturday, June 28, 1890, “Yesterday afternoon Hurst took Duke before a Catholic priest, and the latter took the vow and promised to abstain from the use of intoxicating liquors for an indefinite length of time.  If Duke sticks to his oath—and the probabilities are that he will—he will once more become the popular idol of the cranks that he was last season.”

The Sporting News of October 18, 1890 and The Encyclopedia of Minor League Baseball, edited by Lloyd Johnson and Miles Wolff, published in 1997, show Duke as leading the Western Association with an earned-run average of 0.89.  At the time, earned runs were unofficial and considered an offensive concept rather than a pitching statistic.  According to researcher Cliff Blau, "A run was generally considered earned only if it scored solely as the result of base hits; walks, stolen bases, wild pitches, etc., all made a run unearned."  Because of multiple pitchers in a game, Duke's earned-run total is unknown.  In the other 37 games, he gave up 29 earned runs in 314 innings for an earned-run average of 0.83.  It could be that, with the other three games added in, his ERA matches the 0.89 published in sources named above, although this was achieved under different standards than how an ERA is computed today.
