Paul Purman wrote for the Newspaper Enterprise Association, a Scripps-Howard syndicate, from 1916 through 1918; best known for naming the college All-American Football Team during those years, he also wrote regularly about baseball.
Shortly before the 1917 season, he wrote about Clarence “Pants” Rowland’s plan to make the Chicago White Sox pitching staff more effective that season:
“Rowland is the latest pilot to take a hand in the life of his players off the field. He has issued an order that his pitchers be forbidden from driving automobiles during the playing season.”
Purman said “Baseball’s case against the automobile,” had been a issue that “occupied managers’ minds for many years.”
He said that more than half of current players “own cars and drive them daily” during the season.
“In Cleveland (in 1914) it was charged that the poor showing of the team was due mainly to players paying more attention to their machines than they did to their baseball.”
Purman said despite the concern, Cleveland manager Joe Birmingham “issued no orders against motoring,” and the Naps “finished a poor eighth (51-102).”
Golf, said Purman, was “another thorn in the sides of managers.” He said Bill Carrigan had “issued a blanket order against his men playing golf.” Carrigan’s order, he said, was the result “two or three players who had been warned repeatedly against thinking more of golf than they did their baseball,” and after the Red Sox won the pennant, Purman said:
“It is rumored other managers will fall in line this year.”
After issuing the ban, Rowland told The Chicago Daily News:
“Physicians declare that the strain of handling a steering wheel is injurious to the muscles used in pitching. There is no doubt that a pitcher cannot do himself justice on the mound after several hours as a gasoline pilot. The eyesight also is put to severe test.”
Urban “Red” Faber, Joe Benz, and Eddie Cicotte were said to be the three pitchers who would be most upset with the ban.

The Chicago papers were silent about whether Rowland’s “ban” was enforced throughout 1917, but Cicotte had his finest season, 28-12, 1.53, and Faber and Benz made significant contributions to the World Champion White Sox.
