The Web site added that Rivera will be invited to Spring Training for the Yankees, who have catchers Jorge Posada and Francisco Cervelli on the 40-man roster. Last year's backup to Posada, Jose Molina, filed for free agency in early November.
Rivera, who was non-tendered by the Brewers, batted .228 with two home runs and 14 RBIs while appearing in 41 games in 2009. Considered an offense-minded catcher, Rivera missed 14 games while on the disabled list with an ankle injury in his fourth season in Milwaukee.
The 33-year-old, originally signed as an amateur free agent by the Tigers in 1997, is a career .244 hitter with 69 home runs in seven seasons in the big leagues.
