Moreno pro rates to 5.0 bWAR per 520 at bats and he's doing this at 22-23 through his first full season. He has a lot of additional value because of defence and base running when compared with Kirk. If he has any uptick in power i.e a slugging percentage increase to around .430-.450 then he's virtually an all-star. I think I'd prefer Moreno over Kirk given the extra years of control and the decent running, but i'm still happy with the trade. Deciding between those two is almost a toss up. We have a good one in Varsho at CF and Kirk/Jansen at C.
