Plenty has changed in Red Sox Nation over the last year, but one constant has remained — the team’s star slugger, David Ortiz. Ortiz is ready to start running and do agility drills in January and he’s looking forward to playing with his new teammates that he’s watched for years from the other side of the diamond. Ortiz has high hopes for the 2013 squad, and thinks the team can do some damage if they stay healthy. NESN’s Adam Pellerin caught up with Ortiz, and the designated hitter thinks the Red Sox front office has done a good job in the changes they’ve made so far. Watch the video above to hear all of Ortiz’s thoughts on the 2013 season.
