Alyson Footer is tweeting that Felipe Paulino has agreed to a one-year, $415K split deal for 2010.
Bernardo Fallas explains that a split deal means Paulino will make major-league money while he's on the active roster, and a lower rate while he's in the minors.
The fact that the Astros signed him to a split deal probably means they're hedging their bets, in case Paulino screws up, or Moehler/Banks/Chacin dominates for SP5.
