The Diamondbacks will offer salary arbitration to right-hander Livan Hernandez at today?s deadline, but they neither expect him to accept or particularly want him back. The D-Backs will make the offer because Hernandez is a Type B free agent and as such would bring them a supplemental first-round choice in the 2008 draft as compensation if he signs with another team. Hernandez has until Thursday to decide, but he is expected to reject the offer and test the market because he could sign a long-term contract rather than receive simply a one-year deal from the D-Backs.
