The 2019 Minor League Baseball season ended with a bang for the Giants as the Sacramento River Cats won the Triple-A National Championship on Tuesday night. One day later, a new season begins for some of the best prospects in baseball. The 2019 Arizona Fall League begins Wednesday night with seven Giants minor leaguers -- pitchers Tristan Beck, Tyler Schimpf and Bryce Tucker, catcher Joey Bart, second baseman Jalen Miller and outfielders Jacob Heyward and Heliot Ramos -- playing for the Scottsdale Scorpions.
