Los Angeles obtained the 35-year-old Canadian from the Blue Jays for minor leaguers Andrew Sopko, a right-hander, and Ronny Brito, an infielder. Toronto is sending cash to offset some of the $20 million Martin is owed in the final season of his contract.
A four-time All-Star, Martin was with the Dodgers from 2006-10 and helped lead Los Angeles to three playoff appearances. He signed with the New York Yankees as a free agent after the 2010 season and spent two seasons in the Bronx before playing two seasons with Pittsburgh and four with Toronto.
He started 71 games at catcher and 21 at third base last year, hitting .194 with 10 home runs and 35 RBIs.
Martin was a 17th-round pick by the Dodgers in the 2002 amateur draft.
Overall, Martin’s teams have made the postseason nine times in 13 years. He has caught 1,519 games, including 1,455 starts, which ranks third among active players behind Yadier Molina (1,836) and Brian McCann (1,529).
Sopko, 24, is 27-17 with a 3.61 ERA in four seasons. Brito, 19, signed with the Dodgers as an international free agent from the Dominican Republic on July 2, 2015. In three seasons, he has hit .259 with 15 homers and 104 RBIs.
