Rendezvous Park was built in 1920 as home to the Mesa Jewels. The Jewels would play in an Arizona based amateur league for several years until the team was "upgraded" to professional status as they joined the Arizona State League in 1929. The ASL had begun in 1928 with 4 teams in Bisbee (Warren Ballpark), Phoenix (Riverside Park), Tucson (Hi Corbett Field) and Miami Arizona (Association Park). In 1929 the league expanded by two adding Globe (School Hill Park) and Mesa (Rendezvous Park). The team was led
on the field by Fitzgerald (10 2B, 5 HR, .335), Ernest Lloyd (7 2B, 3 3B, 6 HR, .410) and King (.356), while Sid Oster was their main pitcher putting up 29 games and 161 innings going 10-9, 3.75 on the season. The Mesa Jewels only lasted the one season as the league expanded to Texas renaming themselves the "Arizona-Texas League". Mesa moved to El Paso to become the Texans while Miami moved to Nogales the following year and Albuquerque joined the league in 1932.
