In 1893, Reitz was sold, for $300, by the San Francisco Friscos to the Baltimore Orioles. His five-year tenure at Baltimore included his most notable season, 1894, during which he collected 31 triples. At the time, this tied Dave Orr's mark, set in 1886, for most triples in a single season. Although Chief Wilson surpassed both of them with his 36 triple season in 1912, Reitz and Orr still hold second place for this record. Contributing to Reitz's 31 triples in 1894 were two bases loaded triples he hit in the 3rd and 7th inning on June 4 against the Chicago Colts that led Baltimore to a 12–4 victory. Reitz's two bases loaded triples in a single game matched a feat achieved by Sam Thompson in 1887. The frequency with which Reitz hit triples in 1894 was marked departure from every other season in his career. Excluding his record-tying season, he averaged under six triples per year.
