Yes on Lewis, Kirilloff, Graterol, Balzovic, and Duran (and Arraez). Yes on Larnach. The way to win a WS is to go for it when you have the chance. Just in the last three years: 2018 Boston added Nate Eovaldi, Ian Kinsler, and Steve Pearce 2017 Houston added Francisco Liriano, Tyler Clippard, and Justin Verlander 2016 Chicago added Chris Coghlan, Mike Montgomery, Aroldis Chapman, and Joe Smith. Certainly don't give away top prospects. But if you can impact your team significantly, do it, even if it costs some of those same prospects.
