The Mariners acquired Zavala from the Diamondbacks on Wednesday along with Carlos Vargas in exchange for Eugenio Suarez, Bob Nightengale of USA Today reports.
Zavala was a waiver claim by the Diamondbacks in September but made just four starts during his three and a half weeks with the team. The 30-year-old catcher has a career .622 OPS over parts of four major-league seasons spent mostly with the White Sox. He could open 2024 as Cal Raleigh's backup.
