Earlier this week the Rays held their weekly "Twitter Tuesday" campaign with Principal owner, Stu Sternberg. One the questions asked was about the possibility of extending Kevin Kiermaier.
@RaysBaseball #AskStu I'm sure this is a closed-door conversation, but how intent are you on extending @KKiermaier39's deal with the Rays?
If you haven't done so already, take a look at Danny Russell's article about the value of Kevin Kiermaier. In the article, Danny looks at a potential WAR value, and wonders if it would be worth it to extend the newest face of the franchise.
