Sandoval's agent, Gustavo Vasquez, confirmed on Monday that Sandoval had landed in Boston.
Sandoval, 28, is a free agent after spending the first seven years of his career with the San Francisco Giants. A two-time All-Star, Sandoval won three World Series with the Giants, including in 2014 when he batted .279 with 16 home runs and 73 RBIs. For his career, Sandoval is a .294 hitter with 106 home runs and 462 RBIs. He was also the World Series MVP when the Giants swept the Detroit Tigers in 2012.
Vasquez told the San Francisco Chronicle last week that Sandoval wants a six-year deal in free agency. The Red Sox are reportedly "all-in" to sign Sandoval, who made $8.25 million in 2014, the last of the three-year, $17.15 million deal he signed with the Giants in 2012. Sandoval could reportedly land a contract worth $90 million to $100 million on the open market.
Sandoval reportedly turned down a three-year, $40 million offer from the Giants before the 2014 season. He also rejected a $15.3 million qualifying offer from the club earlier this month.
