Weeks after heart transplant, Red Sox fan to attend Game 2 of World Series

Guleserian said baseball helped provide a distraction to Andrew.

"He was able to focus on something other than being in the hospital," said Guleserian, surgical director of cardiac transplantation at Children's and a professor at the University of Texas Southwestern Medical Center.

Andrew and Guleserian began to talk more earnestly about going to Boston if the Red Sox made it to the World Series and Andrew continued to flourish.

"We'll do our part, and the Red Sox just have to keep winning," said Guleserian, whose family has season tickets to the Red Sox.

Andrew was discharged from the hospital early last week, but he and his mother will stay in Dallas likely until just before Christmas as Andrew undergoes frequent checkups.

"Right now I feel great," said the seventh-grader, who plays catcher, pitcher, third base and outfield. "I've been running around, playing a lot."
