The Pittsburgh Pirates have signed John Jaso to a two-year, $8 million contract.

Jaso, 32, has played mostly in the outfield and at catcher in the past, but the Pirates plan to use him at first base. He has played first in just two Major Leagues games.

"John is enthusiastic about playing in Pittsburgh and developing as a first baseman," Pirates general manager Neal Huntington said. "We feel he has the ability to play the position at the major league level."

Jaso will earn $4 million in each of the next two seasons under the deal. He can make an additional $1 million annually in performance bonuses.
