"Here is the standard Trade Trees style tree for the Brewers dealings with Kevin Mench and Carlos Lee.  Anyone who guessed ""Jesus Pena"" as being the pater familias needs to either get out more or get a job with Elias.  Pena never pitched for the Brewers.  He signed in the 2001-02 off season and was traded before the 2002 season began. Getting all the way to Zack Greinke was a pleasant surprise.  Who would have imagined that signing a FA with 48 career appearances would one day net the Brewers a Cy Young winner?"
