Walt Meinert did pretty well in his four games in the big leagues. With the St. Louis Browns in 1913, he hit .375 (all singles), stole a base and drew a walk. Appearing in right field in two games, he made no errors. However, as Sporting Life reported:
"Disposing of three players was Branch Rickey's first official act after becoming manager of the Browns. He has released Dwight Stone and Schwenk, both pitchers, to Oakland, of the Pacific Coast League, and Meinert, an outfielder, to Houston, of the Texas League."
His name had been misspelled previously by Sporting Life as Meinart.
Walt had played most of 1913 with the Superior Brickmakers. He played in the minors through at least 1925. In 1921 he was with a top company baseball team called the Staley Starch Workers, for whom Joe McGinnity was the manager. 
He was still with the Staley company many years later when he fell to his death in a loading shaft at age 67. His obituary states he had played a number of years for Staley baseball teams. He had also, per the obituary, played for Superior, Houston, Burlington, Ottumwa, LaCrosse and he was with Danville in 1922-1925.
