If a ten year veteran has played his last five seasons with his current team, he cannot be traded without permission because he has ten and five rights. Chipper Jones, for example, doesn't need a formal no-trade clause as long as he's with the Braves because his ten and five rights assure him that no deal will go through without his approval. Carlos Beltran's also a ten-year veteran, but the Mets could deal him without permission if he didn't have a no-trade clause since he won't have played five years in New York until after the 2009 season.
You need to update this because Beltran now has 10 and 5 rights.
Does anyone know if Roy Oswalt has 10 and 5 rights, I know he has the 5 covered, but not sure about total service time.
