Darwin Barney has the lowest BABIP among qualifying players, 3rd lowest among qualifiers in wRC+,16th in GDP (Starlin Castro is 13th). 1st in Fld. Darwin Barney is: last in R, OBP, BABIP, SLG, wOBA, wRC+, and WAR among qualifying second basemen, while being 2nd last in RBI and AVG, and 3rd last in .ISO among qualifying second basemen. Cano, Zobrist(option), Infante, and Kendrick are all available in the off season. We can pitch Barney to a team in a trade to shore up their defense while creating a roster spot for us.
Luis Valbuena would profile very well at 2B, as he'd be (min 350 PA): tied for last in GDP, 1st in BB%, 3rd in Fld, 9th in .ISO, tied for 10th in OBP and HR, 13th in WAR, 15th in wOBA, 16th in wRC+, 17th in SLG, while being 3rd lowest BABIP, 5th lowest .AVG, tied for 11th in K%, and 22nd in BsR. I think a platoon with Donnie Murphy would be very successful there and cost-effective. I believe Valbuena will be on his 2nd year of arbitration eligibility and Murphy will be on his first. If the Cubs decide that Javier Baez is better suited at 2B than 3B, no problem.
I think trading for CarGo is a great idea. He doesn't need platooned, has speed, has a reasonable contract and can be that veteran presence for our club. The Rockies need another starter and Jeff Samardzija would be a perfect fit in Colorado. They're going to end up having an OF of Dickerson/Fowler/Blackmon for their future and Cuddyer/CarGo will be traded this off season. A three way trade that involves sending Schierholtz somewhere would make this happen.
Rajai Davis will be a free agent next year and has been a consistent platoon outfielder vs LHP the past five years with the numbers to back it up. He'd be a great acquisition to fill the Hairston/Gillespie/Neal/Sappelt role-but with actual results around the same contract.
I'm going to guess that Ryan Sweeney will sign elsewhere, but we can retain Dioner Navarro and Scott Baker on two-year deals.
