The late Roland Hemond, a legendary and longtime general manager, used to say the trades that worried him the most were the ones in which he was lavished with immediate praise for having made a one-sided deal.
Under the Hemond proviso, the Mariners should be quite worried right now, because their trade on Wednesday with the Toronto Blue Jays for Teoscar Hernandez seems heavily weighted in their favor. That seemed to be the instant feedback on social media and beyond.
The Mariners gave up reliever Erik Swanson and minor-league pitcher Adam Macko to get Hernandez, the sort of highly productive power bat for which they have been clamoring. In present-day value, this trade is a home run for the Mariners (who no doubt remember the two home runs Hernandez hit against them in Game 2 of the American League Wild Card Series in October).
