One cannot interfere with a foul ball.
It's even debatable whether the ball was in foul territory or in the stands.
It did not cost the Cubs the pennant. They gave up 8 runs in that inning, losing by 5. Unless you're willing to blame 6 runs on that guy, it didn't even cost them the game.
Lots of people around him were trying to get the ball too.
