The New York Mets completely blew it last night. Behind that loss was a a number of players failing. Todd Frazier couldn’t get a hit in two key RBI situations. Steven Matz allowed a grand slam. Brad Brach failed to cover first in time. There’s obviously more.

Behind the players failing was a number of questionable to flat out indefensible decisions from Mickey Callaway.

Callaway should not have let Matz face Jorge Alfaro. With the team having zero margin for error, you cannot use Walker Lockett under any circumstance. There’s no saving the top arms in the bullpen to fight for another day because if you lose, there isn’t going to be another day.

There were other decisions like not starting Brandon Nimmo or allowing Michael Conforto to bat against Brian Moran. You could also question using Rajai Davis as a pinch hitter in the sixth over Nimmo. To be fair, these decisions were mitigated by Juan Lagares going 1-for-3 with a run and a walk, and Amed Rosario hitting a grand slam.

The pinch hitting decisions were mitigated by the actual options available. Tomas Nido and Rene Rivera are not good hitters. Jed Lowrie hasn’t had a hit in his limited pinch hitting appearances, and he has just one right-handed at-bat all year. That’s it for the right-handed bench options against the left-handed pitching the Marlins had out there in the form of Caleb Smith and Moran.

It certainly makes you question why the Mets never made a roster move to add Dilson Herrera to the roster. After all, they lost Eric Hanhold so they can have Chris Mazza and Donnie Hart on the roster, neither of whom have pitched one meaningful inning in September.

Taking that into consideration, you have to look at the bullpen again. Seth Lugo and Justin Wilson are the only reliable arms down there. You can trust Brach against right-handed batters but not left, and vice versa for Luis Avilan. After that, it’s a straight roll of the dice. Sadly, it’s a heavily weighted pair of dice putting the odds stacked against the Mets.

Look at those ERAs again. Lockett wasn’t even the worst ERA available in the bullpen last night. He wasn’t the only one with an ERA over 5.00. In fact, taking away the top two relievers, there were only three relievers with an ERA under that mark, and one of those, Hart, has only pitched 1.0 innings.

Put aside for a moment the Mets entered the season with Tim Peterson in the bullpen putting the team 1-2 relievers short to start the season. At the trade deadline, the Mets went out and got Marcus Stroman, and they didn’t back it up with another move. Sure, they got Brach, but he fell into their laps. It wasn’t a proactive move on the Mets part.

The bench has always been an issue too. We have seen the Mets cycle through Aaron Altherr, Keon Broxton, Carlos Gomez, Adeiny Hechavarria, and Ruben Tejada while rage cutting Travis d’Arnaud. Again, the Mets did little to address this at the trade deadline with Joe Panik falling into their laps like Brach did.

This team was ill constructed from the get-go, and for some reason when the Mets doubled down at the trade deadline, they did nothing to fix their two biggest problems – the bench and the bullpen.

Now, it’s possible a very good manager like Terry Francona or Bruce Bochy could’ve navigated their way around these problems, but we know Callaway couldn’t. The Mets knowing that and handing him a roster which feeds into his deficiencies as a manager makes what Brodie Van Wagenen did all the worse.

So, yes, Callaway screwed up yesterday, and he has screwed up in other spots. But make no mistake, this was largely the result of the roster he was given. For that, Brodie Van Wagenen should shoulder the blame he was absolutely unwilling to accept earlier in the year.
