Chicago Cubs top pitching prospect Andrew Cashner was recently moved from the AAA Iowa rotation to the bullpen, in what many viewed as a precursor to a call-up to the big league pen. Baseball Prospectus’ Kevin Goldstein says he’s heard that the Cubs plan to call Cashner up on Monday to join them for the upcoming Pittsburgh series.

Whom he would replace is a subject of debate – the obvious answer is miserably performing John Grabow, but thanks to a two-year contract, Grabow is unlikely to be released. Perhaps an “injury” is in order.
