Baseball-reference.com has two listings for players named Emil Moscowitz: 1929-1931 and 1949-1950. Despite the 17 year gap they are the same player. According to the February 18, 1948 issue of the Sporting News, Moscowitz was signed as a teenager by the Yankees and spent parts of 3 years in the lower minors as part of their farm system. He hurt his arm, lost his effectiveness, and returned to his home in New York where he played semipro ball. He gradually regained his abilities and developed a reputation as an exceptional control pitcher. He reached the pinnacle of semipro/independent baseball in the area in 1944-47 pitching with the Brooklyn Bushwicks, playing alongside former major leaguers and in exhibitions against Negro major league teams. In 1948 he was signed by the Yankees as batting practice pitcher. One of the pictures is from the Yanks' team picture of that year. In 1949 and 1950 he played in the class B Colonial League, the nearest league to New York City, where he was arguably the league's dominant pitcher, leading that league in ERA and Won-Lost Percentage both years and strikeouts as well in 1950. When the league folded after the 1950 season, Moscowitz, now nearly 40, once again retired from the professional ranks.
