There is no rule against kicking a ball to another fielder. Is there any rule that indicates that might be against the spirit of the game? What happens if I allow it? What happens if I don't allow it? Those are the questions an umpire should be asking before making an unusual ruling.
That's a lot to process in the time necessary to decide a call and, in this situation, potentially a huge argument if you decided not to allow it without a rule or case play backing up that call. I can think of at least three completely legal and accepted ways for the ball to get from one player to another without being thrown (with the throwing arm) directly into a glove. Why would a kick be any different?
