On Dec. 15, the Boston Red Sox made their annual holiday visit to Mass General for Children’s inpatient units. The pitching staff, including Heath Hembree, Brian Johnson, Austin Maddox and Robby Scott, accompanied by Wally the Green Monster and his sister, Tessie the Green Monster, played pinball with patients, posed for photographs and gifted each child a signed baseball. The tradition dates back to 2002 when the Fenway Sports Group acquired the team.
