Dec. 3, 1968: On this day 44 years ago, Major League Baseball approved its rules changes. Big deal.
Oh, but this time it was. After a season "completely owned by pitchers," in the words of "Sports Illustrated" back then -- owned most notably by the Detroit Tigers' Denny McLain (31-6, 1.98 ERA and 280 strikeouts in 336 innings) and the St. Louis Cardinals' Bob Gibson (22-9, 1.12, 268 K in 304.2 innings), both of whom won Cy Young and MVP awards -- MLB decided to lower all mounds from 15 inches high to 10.
And it seemed to work; scoring went up by 0.6 runs per team per game -- almost 20 percent -- in both leagues, while McLain's and Gibson's ERAs increased significantly (to 2.80 and 2.18, respectively).
