You may want to get upset with Edwin Diaz for blowing a game the Mets probably needed in the worst way. The team was about to get over .500, and they were going to earn at least a split in a road series against the best team in the National League. Instead, despite being ahead in the count against the six batters he actually faced, he would not record an out until Alex Verdugo‘s game winning sacrifice fly.

Entering the game, Diaz’s stats looked great. He was 1-2 converting 13/14 save attempts with a 1.64 ERA, 1.045 WHIP, and a 14.3 K/9. After his performance against the Dodgers, he looks much more like a mediocre reliever with a 3.22 ERA and a 1.299 WHIP.

However, Diaz is not mediocre. As we’ve seen with the Mets and his time with the Mariners, he is a lights out closer who comes in a strikes out the side. With how he’s performed, many have made the assertion he is the best closer in baseball. Diaz has made his case, but that is something which is far from a certainty.

Before proceeding, it is extremely important to note Diaz has been under a heavy workload. He has appeared eight times over an 11 day span, and that does not include the times he has been dry humped. What his stats now are reflect the wear and tear and fatigue which has been the result of how he has been used recently. In reality, it would be unfair to criticize him for not being able to withstand this stretch, and really it’s unfair to criticize him for one bad outing.

Still, there are some warning signs when it comes to Diaz.

Already this season, Diaz has allowed five homers which is the same amount as he did all of last year. It should some as no surprise his 25.0% HR/FB already stands as a career worst. The 55.6% hard hit rate is also a career worst. He’s allowing more line drives and getting fewer ground balls. Some of that is reflective of last night, and some of that is reflective of him not being quite the guy he was last year.

When you look at Diaz’s young career, you see two really good seasons and one average one. Certainly, with this being just his fourth season, it is too early to suggest this is a pattern and this will be a mediocre year. After all, he was dominant over his first 24 appearances. It is way too soon to suggest yesterday was more than a blip.

However, it is also too soon to suggest he’s not going to regress from what he was over his first 24 appearances. He is getting hit harder, and he is bowing under the workload, a workload which admittedly could be too much for any closer. Still, fair or not, this is what the Mets need from him right now, and at least last night, he didn’t deliver.

Overall, it is way too soon to suggest there is more to yesterday than just one bad outing. Diaz has two great seasons, and he had a great start to the season. Still, there are warning signs. Hopefully, this is just a blip on what should be a great year for someone we believe to be a great closer. Time will certainly tell.

The one thing we do know is Diaz isn’t perfect. Mickey Callaway needs to back off to get Diaz back to back to being the pitcher he can be. In order for that to happen Brodie Van Wagenen has to do his job and get his manager some reliable arms in that bullpen. If that happens, there should be no causes for concern. If it doesn’t, well, we will see what happens.
