Yankees nation rallied together for CC Sabathia on Thursday -- using their star power to raise $1 MILLION for the pitcher's charity organization ... despite a torrential downpour!
Stars like Jennifer Lopez, Alex Rodriguez and Victor Cruz teamed up with Aaron Judge, Amar'e Stoudemire, Saquon Barkley, Leslie Jones and Mariano Rivera to play in a softball game at Yankees Stadium.
And get this, Meek Mill's attorney Joe Tacopina also got the VIP treatment -- posing for pics with the likes of Giancarlo Stanton. Tacopina was actually named co-MVP of the game!
There was also a moment of silence to honor Lesandro "Junior" Guzman-Feliz -- the teenager who was stabbed to death by gang members earlier this month in the Bronx.
CC's charity -- PitCCh In -- focuses on helping underprivileged kids in inner city communities.
