Editorial Note: Stuff as a term for a pitcher’s ball delivery has a long history in baseball, dating to at least as early as 1905. Filthy stuff is also a euphemism for money.

Boston Globe (Sept. 26) “It’s the crowning blow” p. D5: It’s a lot more fun catching Clemens than it is hitting against him. Roger was nasty. He had filthy stuff. 2003 Dan Mcgrath Chicago Tribune (Sept. 7) “The Arm And The Man” p. 13: Clemens, from the Houston suburb of Katy, is his acknowledged heir with 300 wins, 4,000 strikeouts and a nasty disposition, still dealing “filthy” stuff and still intimidating hitters at age 41. 2004 John Crowley Examiner (San Francisco, California) (June 23) “Giants take over 1st”: Other than a pitcher with “filthy stuff,” as they say in dugout parlance, nothing can kill a hitting streak like over-analysis.
