Red Sox, Ross agree to two-year deal

David Ross is considered perhaps the best backup catcher in baseball. And now he is joining the Boston Red Sox.

Ross reached agreement Saturday with the Red Sox on a two-year, $6.2 million free-agent contract, according to major-league sources.

Ross will be "more than a backup but not a starter" for the Red Sox, according to one source. The Sox could move one of their current catchers, Jarrod Saltalamacchia or Ryan Lavarnway. The team’s plans are unclear.

The deal will become official once Ross passes a physical, ending his four-year tenure with the Atlanta Braves.

Ross, 35, played briefly for the Red Sox in 2008, signing with them in late August after getting released by the Cincinnati Reds.

The Red Sox allowed him to become a free agent at the end of that season, and Ross signed with the Braves. His most recent deal with Atlanta was for two years, $3.25 million.

Ross batted .256 with a .770 OPS in 196 at-bats as Brian McCann’s backup last season. The Braves now must find another catcher. McCann underwent surgery to repair a torn labrum last month, but the Braves expect him back in the first month of next season.
