» December 12, 1911: A rift between the leagues develops over widespread charges of ticket speculation during the World Series, and accusations that officials of the Giants and A's were involved. The American League passes a resolution refusing to participate in another World Series until it has control of ticket sales in its own parks. The National Commission investigates the charge that speculators were given large blocks of tickets, but takes no action and releases no findings. The following spring, the Commission finds that much scalping occurred, but there is no evidence either team was involved, and peace is declared.
» December 14, 1911: Pirates owner Barney Dreyfuss proposes that each team in the World Series be required to turn over one-fourth of its share of the gate to the league, to be divided among the other teams. Until now, 10 percent of the gross has gone to the National Commission, 60 percent to the players, and the rest to the two pennant-winning clubs. The National League will pass the resolution and send it to the American League. It marks the beginning of changes that ultimately give players of the first four clubs a percentage of the World Series money.

In today's doubleheader, the Cardinals had taken the first game 5–2, and the 2nd game, and the 2nd game is tied 1–1 after four innings when a brawl broke out. Since there had been several other fights in the series, and because the series was played outside the auspices of the National Commission, the umps announce they have had it, and retire to the clubhouse. The series ends abruptly at three wins apiece, with one tie. Each Brownie player received $77.22.
» January 6, 1914: The National Commission grants some demands of the Players' Fraternity: players to be notified in writing of their transfer or release and to receive a copy of their contract; players with 10 years in the ML are eligible to become free agents; clubs will pay traveling expenses to spring training and furnish all uniforms; all parks to have a blank green wall behind the pitcher in CF.

» June 17, 1918:
The National Commission rules that P Scott Perry,
who has been winning games for the Athletics, belongs to the Boston Braves. Although purchased by the Braves from Atlanta in 1917, the deal was not completed. While on Atlanta's ineligible list, he was sold to Connie Mack. Aroused by Perry's AL success, the Braves enter their proper claim. Mack breaks precedent, goes outside organized baseball to civil court, and gets an injunction against Boston. The NL, having sat still for the loss of George Sisler, is furious; President John K. Tener resigns. John Heydler succeeds him and arranges a compromise solution: Mack pays Boston $2,500 and keeps Perry (henceforth a loser). The clubs' anger at player-allocation decisions will ultimately topple the National Commission, making way for Judge K.M. Landis.

» July 13, 1919:
Submarine P Carl Mays quits the mound after two innings at Chicago, blaming his teammates for lack of support afield. In defiance of Ban Johnson's order that no action be taken until Mays is returned to good standing, Boston owner Harry Frazee trades Mays to the Yankees for pitchers Bob McGraw Allen Russell and $40,000. Johnson suspends Mays indefinitely and orders umpires not to let him pitch for New York. The Yankees get a court order restraining Johnson from interfering, further eroding Johnson's authority and standing. The AL directors will reinstate Mays. In retaliation, on October 29th the National Commission will refuse to recognize the Yankees' third-place finish and will withhold the players' share of the pool. New York's owners will pay out of their own pockets.
» September 2, 1919:
The National Commission recommends a best-of-9 World Series. The lengthier WS is seen as a sign of greed and is abandoned after three years.
» February 12, 1920:
In a defeat for American League president Johnson, Carl Mays is reinstated, and the Yankees' 3rd place finish is recognized. Furthermore, a two man committee is appointed to review all fines over $100 and suspensions of more than 10 days. Dissatisfaction with the National Commission system comes to a head. The National League votes 6–2 for a one-man commission; the AL votes 6–2 for the status quo. Chairman Garry Herrmann resigns, stating his belief that no club owner should serve on the governing board. When the two leagues cannot agree on a chairman, it is left to the league presidents to decide disputes.
» October 24, 1927:
August "Garry" Herrmann, former chairman of the
National Commission and 25-year Reds president, resigns.
