Pedro Astacio, claimed of waivers from the Texas Rangers in June, was a pleasant surprise for the Padres down the stretch, going 4-2 with a 3.17 ERA.
Hernandez and Astacio have until December 19 to decide whether to accept the arbitration offer. If they don't accept, the Padres may still negotiate with each through January 8. Should Hernandez depart for another organization, the Padres would get two compensation draft picks for losing him.
Joe Randa, Chris Hammond, Rudy Seanez and Robert Fick, also free agents, were not offered arbitration, essentially ending their tenure with the club. Randa and Seanez were both Class A free agents, and Hammond Class B, meaning the club forfeits the chance of five total compensatory draft picks by not offering arbitration. The club may not negotiate with any of these players again until after May 1.
