The Twins called up outfielders Ben Revere and Brian Dinkleman and infielder Luke Hughes from triple-A Rochester Thursday and this is only the beginning of auditions for the Twins who are 19-games under 500.  Anthony Swarzak is getting his audition as a starter now and we may see an audition for Kyle Gibson later this season.  The Twins could also take a look a Carlos Gutierrez out of the bullpen.  Teams that are out of the race need to find out what they have in certain players and the Twins are no exception.  Revere could make Delmon Young expendable if he seizing the opportunity.  Swarzak and Gibson could perform well enough where the Twins consider trading Pavano and/or Liriano.  Tsuyoshi Niskioka will get an audition at shortstop when he is healthy enough.  The only thing the Twins have to lose with these auditions are games and they are already doing that.
