Martin Glendon struggled in his first major league game with the Cincinnati Reds in 1902, but followed that up with three more big league games with the Cleveland Naps in 1903, in which he did well, posting an ERA of 0.98. However, he gave up several unearned runs and ended up losing two of those three games.
Martin was pitching in the minors by 1898, and after his one game with the 1902 Reds went 23-20 for the San Francisco team in 1902. He stayed with San Francisco for much of 1903, coming then to the 1903 Naps. He then pitched in the minors through at least 1907.
This site  has quite a detailed biography of Glendon. Among other things, it points out that Martin had a brother named Dick who was also a pitcher, and on occasion, people confused one with the other. Also, a pitcher called "Burns Glendon" and "Buns Glendon" might have been Martin. Burns Glendon was touted by Hank O'Day to the 1901 Chicago Orphans and signed to a minor league contract. Burns Glendon was said to be a prize fighter in the winter. At various times, Martin also worked as a brakeman, a semi-pro ballplayer, a bartender and an electrician. In 1940 he was still working as an electrician for the City of Chicago.
