The Los Angeles Angels are dead last in the AL West right now ... and here's Halos superfan ScHoolboy Q to passionately explain what needs to happen to turn things around!!

"Get some pitching," the "Numb Numb Juice" rapper told TMZ Sports out in NYC on Thursday.

"You can't win if you can't strike nobody out and stop walking people and then people hit the sh*t over the f*cking gate."

Q is a MASSIVE Angels fan -- he's even thrown out the ceremonial first pitch!!

Q's got a point -- the Angels' team ERA is one of the worst in the league with nearly 5 runs allowed per game.

L.A.'s 2-8 in their last 10 games -- they'll have to make it all season without their superstar pitcher Shohei Ohtani ... and the players ain't the only guys missing him.
