Chili Davis, Oakland's hitting coach the last three seasons, has been hired to the same position by the Boston Red Sox. The club made the deal official on Thursday.
The Red Sox are believed to have agreed to a multiyear contract with Davis, who had also been courted by the Yankees and Rangers for their vacant hitting coach jobs.
Davis, 55, served as hitting coach for Boston's Triple-A affiliate in Pawtucket in 2011 before returning to the Majors as Bob Melvin's hitting coach.
The Red Sox have been seeking a replacement since Greg Colbrunn resigned on Oct. 3.
Under Colbrunn, the Red Sox rode one of the American League's strongest offenses to the 2013 World Series championship. In 2014, Boston scored 219 fewer runs, tying for 11th in the American League with 634.
