Because Ashby, 37, is a 10-and-five player--he has 10 years in the majors and at least five with the same club--he has the right to veto any trade if he wishes.
"Alan Ashby is well-established (in Houston) with a home and his family there," Pirates' General Manager Larry Doughty said. "He has a new home and a new baby. He just bought into a golf course."
Ashby reportedly would have accepted the trade if the Pirates would have significantly increased his $550,000 yearly salary. Doughty said the Pirates offered a raise, but it wasn't "outlandish."
The Pirates need a left-handed hitting catcher because Mike LaValliere is out until at least the All-Star break following knee surgery. Manager Jim Leyland has been alternating right-handed hitting catchers Junior Ortiz and Tom Prince.
