The Arizona Diamondbacks have finalized an $8.25 million, two-year contract with free agent catcher Alex Avila .
Avila fills a roster spot vacated by Chris Iannetta , who shared the catching duties last year and left for an $8.5 million, two-year deal with Colorado.
The 31-year-old Avila, a son of Detroit general manager Al Avila, hit .264 with 14 homers and 49 RBIs last year for the Tigers and Chicago Cubs , who acquired him at the July 31 trade deadline. He is a .243 hitter in nine major league seasons.
Avila joins Jeff Mathis and Chris Herrmann as the Diamondbacks' catchers.
