But Dave Dombrowski has never been afraid to go down swinging, and on Monday he struck a deal he hopes will revive Philly's flagging offense, acquiring second baseman Luis Arraez and righty reliever Caleb Kilian from the San Francisco Giants. The Phillies have been in desperate need of somebody who can get on base consistently, and Arraez certainly fits the bill there, although the trade does come with some important fit questions. Phillies give flagging offense a needed boost with Luis Arraez trade, but fit questions persistThe defensive downside here is immediately obvious, given that Harper is now 33 and Stott is being asked to move off of a position at which he's excelled. Would it have been nice for that upgrade to come in the form of a righty-hitting outfielder? That's pretty tidy work for a rental from Buster Posey and Co.Phillies trade grade: C+Giants trade grade: B+
