I'm a little embarrassed to ask this as I ought to know better, but here's what I've got.

I have an object "Pitcher" with an int property of "runsAllowed". I have an object Batter that has a property of "responsiblePitcher". I have an object Team that has a property "pitcher". When the batter reaches base:

Batter.responsiblePitcher = Team.pitcher;

All that's well and good. However, if we have a pitching change while the runner is on base, I set a new pitcher in Team.pitcher:

Team.pitcher = new Pitcher();

... and of course this changes the value of Batter.pitcher.

How should I be doing things differently such that the Batter.responsiblePitcher property continues to point to the pitcher who let him on base instead of pointing at whever is in the Team.pitcher property? Again, I feel like I ought to know this already ...

Thanks.
