Major League Baseball lowered the pitchers mound height from 15 inches to 10 inches, 51 years ago today.
The rule change was part of a response to the issue of pitching becoming too dominant in the NL and AL, as evidenced by five no-hitters thrown during the 1968 season:
1 | Tom Phoebus |
---|---|
Baltimore Orioles (AL) | |
Saturday, April 27, 1968 Baltimore Orioles 6, Boston Red Sox 0 Memorial Stadium (Baltimore) |
|
2 | Jim “Catfish” Hunter |
Oakland Athletics (AL) | |
Wednesday, May 8, 1968 Oakland Athletics 4, Minnesota Twins 0 Oakland–Alameda County Coliseum (Oakland) (Perfect game) |
|
3 | George Culver |
Cincinnati Reds (NL) | |
Monday, July 29, 1968 (Second game of doubleheader) Cincinnati Reds 6, Philadelphia Phillies 1 Connie Mack Stadium (Philadelphia) |
|
4 | Gaylord Perry |
San Francisco Giants (NL) | |
Tuesday, September 17, 1968 San Francisco Giants 1, St. Louis Cardinals 0 Candlestick Park (San Francisco) |
|
5 | Ray Washburn |
St. Louis Cardinals (NL) | |
Wednesday, September 18, 1968 St. Louis Cardinals 2, San Francisco Giants 0 Candlestick Park (San Francisco) |
Other rule changes required the slope of the mound to be uniform and gradual and reduced the size of the strike zone to the armpits to the top of the knees.
Los Angeles Dodgers pitcher Don Drysdale criticized the changes.
“If they think this is going to make .300 hitters, they’re mistaken,” Drysdale told the Associated Press. “Last year could have been just a one-year thing. I think they should have waited a year to see how it goes before panicking like this.”
So how did the moves work? Well, 1969 did see an uptick in runs scored, but no-hitters actually increased by one and three pitchers notched their second career no-nos!

Things didn’t work out for Drysdale, either. After an All-Star season in ’68, Drysdale battled through arm soreness until finally hanging up the cleats in August of ’69.
It’s interesting to note that both the year before the rule changes, ’68, and the year after, ’69, are the only seasons in MLB history to see teams exchange no-hitters on consecutive days, Perry/Washburn in ’68 and Maloney/Wilson in ’69.
Editor: Headline says that mound was lowered by FIVE FEET, not five inches
I’ve always thought it would be fun to have the pitcher start underground! Thanks for the catch; that’s fixed.
