A good major league team needs 4 full-time outfielders. In the case of the Twins, I see their outfield in the next few years as Buxton, Celestino, and two of Larnach, Kiriloff, and Kepler. That gives us 2 RHB, 2 LHB, and three (including Kepler) who can play CF. Keep all five, and Kiriloff also becomes part of a platoon at 1B with Sano and gives the team a good overall rotation at DH. That said, go ahead and trade anyone if the price is right.
