Mets' Offseason Edwin Diaz-Robinson Cano Trade Could Go Down as One of the Worst Ever

It took all of four months for GM Brodie Van Wagenan to be exposed as a snake oil salesman after an offseason in which he promised Mets fans the world. On the surface, adding one of the best closers in baseball in Edwin Diaz and planting Robinson Cano in the black hole of production that was the Mets' second base situation after Daniel Murphy left seemed like an amazing deal.

With the only major costs being an inconsistent arm in Justin Dunn (who has put together a nice season in Double-A this year) and a prospect in Jarred Kelenic who wouldn't see MLB action for several years (though is now said to be ahead of his timetable to reach the bigs), this was a steal by the Mets, right? Well, quite the opposite, Cano and Diaz are in the middle of the worst seasons of their respective careers, and Diaz has found himself on the trading block again.

Classic Mets doesn't even begin to describe this.

Diaz's ERA has ballooned from 1.96 last year to 4.81 this year. Cano's .254 average , nine home runs, and 90 OPS+ are bad enough, but when you factor out the three home runs he had yesterday, those numbers look even more putrid.

This is the worst-case scenario for the Mets. Cano's contract is so untradeable Seattle has to throw a guy with 57 saves into a deal just to offload it. Diaz looks lost and in a funk now that he can't command his slider. Meanwhile, Dunn has a 3.46 ERA for the Double-A Arkansas Travelers, while Kelenic is hitting .285 with 15 home runs this year. Both Dunn and Kelenic were Futures Game participants.

The graveyard of star players who lost their superpowers after joining the Mets could gain two new members, unless they reverse the trend as soon as possible.
