After the Boston Red Sox added another year to David Ortiz's contract, Ben Cherington guaranteed that the slugger would retire with the club.

Ortiz will make $16 million next season, with options for the 2016 and 2017 campaigns.

"We just felt like if we were going to talk about this now, let's see if we can find a way to craft something fair to David and virtually guarantees he finishes his career here," said Cherington, who cited Ortiz as a "cornerstone player" and invoked his value to the franchise beyond the playing field.

"That was the goal. That's what we set out to do, and I'm glad we were able to accomplish that."
