Fantasy keeper league help?

In my league you're allowed to carry three people over into the next season. I need to decide between Adrian Gonzalez (keep), Jose Reyes(keep), Dustin Pedroia (?), Adrian Beltre (?), Carl Crawford (?), and Jacoby Ellsbury (?) Who should be my third keeper? And yeah I know there are a lot of red sox, but that's my team and I've gotta show the love. Haha
