The fact that the ball lodged as opposed to naturally hit the wall and rolled back on to the playing field enabled the runners to get an extra base.
Because the player threw his hands up and didn’t play the ball the runners were able to score.
So you go back to what if the ball didn’t lodge? The Umpire makes the decision runners on 2nd and 3rd.
Since the ball was lodged, it required to outfielder to run all the way to the fence, as opposed to if the ball bounces off the wall, the ball moves toward the outfielder, which allows him to throw the ball back to the infield sooner.
