In 1947, Ritchey made his professional debut with the
Chicago American Giants of the Negro American League. He posted a .381
batting average to lead the circuit, edging
Birmingham Black Barons star
shortstop Artie Wilson by just .008, as
Jackie Robinson was making history and breaking the
Color Barrier in Major League Baseball. Ritchey made history soon later, becoming the first ever African American to play in the Pacific Coast League. In his rookie season, Ritchey would be in competition for the catching duties with veterans
Hank Camelli and
Len Rice, who were injured during
spring training and Ritchey caught nearly the entirety of the season-opening series against the rival
Los Angeles Angels. Not typically a power hitter, Ritchey went 8-for-16, including a game-winning, three-run
home run in one contest. Thereafter, Ritchey played for the
Portland Beavers in part of two seasons spanning 1950–1951. In 1950, he slashed .270/.389/.361 with two homers and 34 RBI in 107 games. Ritchey came back to Vancouver in 1952 and hit .343/.504/.447 in 137 games, including career-highs with 96 runs, eight
triples and 27 stolen bases, once more receiving again more walks than strikeouts (144 to 30). He almost repeated as batting champion, losing the title just by .009 points. After that, Ritchey had a second stint in the PCL, playing three seasons for the
Sacramento Solons and
San Francisco Seals from 1953 through 1955. Overall. he hit .347 and slugged .469 during the two seasons. Ritchie spent his final season in the
Eastern League in 1956, appearing in 16 games for the
Syracuse Chiefs and hitting .185 (10-for-54) with two doubles. ==Post-playing career==
