"One of the famous freaks of the game was the nail on the fence of the Sunday grounds at St. Paul . . . (Frank) Isbell says he was pitching . . . (and a) batter drove a fly (which) stuck on a wire nail . . . practically the same thing happened while Roger Denzer was pitching a game, the ball impaling itself on the same nail . . . Denzer, after the game, procured a hammer and bent the nail and Isbell, in telling the story, always offered to show a bent nail in the fence to prove it." - from the Atlanta Constitution, August 17, 1919
Roger "Peaceful Valley" Denzer went 4-14 in the majors but had more success in the minors, going 33-10 for St. Paul in 1898 and 20-10 for the Chicago White Stockings of the new minor-league American League in 1900.
He pitched for manager Cap Anson in 1897 and did better than one might think: his 5.13 ERA was not too much higher than the team ERA of 4.53. He was two years younger than fellow pitcher Clark Griffith.
According to a blurb in the April 26, 1897 edition of The Lewiston Daily Sun, Roger got the nickname "Peaceful Valley" because that was the title of a play being performed at the time and Roger supposedly resembled one of the actors.
