I hope you guys realize WAR doesn't actually equal wins. A teams total WAR varies from about 10-65. Or at least that is what it appears like on Fangraphs. Going off WAR the Astros won 65 games, us about 32, and the Marlins were a stellar 10 win team. If you look at ours each WAR was actually worth about 2.7 wins. So a .7 difference between Shaw and Hiura was worth 1.8999 wins. Considering we arguably punted the last game because it meant nothing you could argue, yes, Hiura getting sent down arguably costed them the division...or a shot at it. Of course we will never know what impact that may or may not have had in reality. He could have batted terribly in moments it mattered (or fielded horribly) costing us multiple games, not actually helping us. You also could play the what if game until the 2020 season starts with all the things we did wrong over the course of 162 games, the offseason prior, the deadline, and anything in between. That is if you really insist on using WAR to calculate wins...I wouldn't...but that is just me.
