Thus far, we have looked at the Mariners trades from the last off-season and discovered that based on WAR output, GM Jerry Dipoto actually “won” the 3 trades we have reviewed for 2019. The three deals we have covered are the Edwin Diaz and Robinson Cano trade, the Alex Colome trade, and the Jean Segura trade.
In all three cases, the Mariners actually gained WAR for the 2019 season by making these trades. Now, we have covered this in every article but it does bear repeating: our methodology is flawed.
