Why would Kristian Campbell potentially sacrifice future value to sign a big extension a week into his MLB career? He offered a simple explanation Saturday.

The Red Sox have agreed to a long-term contract extension with Kristian Campbell on Wednesday, just five games into the top prospect's MLB career. And for very good reason.

You can see how well Campbell is fitting in and getting along with his teammates as well. During the interview, you can hear Red Sox All-Star left fielder Jarren Duran shout something and Campbell responds with, "That was Duran, he's bugging me right now."
