The Nationals selected Noll in the seventh round of the 2016 Major League Baseball draft, making him the fifth-highest draft pick in Florida Gulf Coast history and the second-highest among position players. Many prognosticators had expected him to be drafted a round or two higher. Noll chose to sign with the Nationals and was named among the organization's Minor League Baseball All-Stars at the end of the 2016 season, progressing from the Class A Short Season Auburn Doubledays up to the Class A Full Season Hagerstown Suns over the course of his campaign. Noll continued his development in 2017, ending the year with the Class A-Advanced Potomac Nationals. Noll was one of six Potomac Nationals honored as Carolina League All-Stars in 2018. He played for the Salt River Rafters in the Arizona Fall League following the 2018 season.
