Among the lower-priority holes currently residing on the Red Sox roster is the lack of a fourth outfielder. It’s not a huge issue for Boston right now for a couple of reasons. For one thing, the starting outfield as currently constructed is one of the best and most exciting in all of baseball. With the defensive versatility and offensive upside at all three spots, there isn’t much of a reason to want to sit them unless it’s absolutely necessary. Additionally, it’s not as if the Red Sox got much from Chris Young last year. There’s not a lot of production to be replaced.
