The Evolution of Edwin Diaz

One of the most infamous trades in Mets history took place on December 3, 2018 when they traded OF Jay Bruce, RP Anthony Swarzak, and three of their top prospects to Seattle for two players: 36 year old 2B Robinson Cano and young stud closer Edwin Diaz. This trade has been dissected endlessly by the baseball media and Mets fans. As soon as the trade was finalized, it was distressing to learn the Mets were taking on the remainder of Robinson Cano's contract, which was 5 years and $120 million. So, the hope was Diaz would emerge as a great closer. Not a good one, but an elite closer. And that's what he had been in his years as a Mariner. Here are some of Diaz' stats from 2016-2018.

3 years in Seattle
2.64 ERA
14.2 K/9
109 saves
12 blown saves
90 save percentage

And his first season, 2019, was one of the most disappointing in team history. Let's look at those numbers.

2019
58 innings
26 saves
7 blown saves
78 save percentage
58 hits
15 home runs
36 earned runs
5.59 ERA
22 walks
99 strikeouts
15.4 K/9
1.38 WHIP

Diaz basically blew 1 out of every 4 save attempts. But deeper than that, he allowed a home run every 3.9 innings and his ERA doubled. There were many Mets fans who wanted him off the team. Sure he could throw the ball hard, but baseball is littered with closers who throw hard and fail in pivotal games. They thought he could not handle New York. Well, did those numbers get better in 2020 and 2021? Let's take a look.

First 3 years with the Mets (2019-2021)
3.23 ERA, down 2.36 from 2019
14.6 K/9, slightly down
20 HR, he only allowed 5 home runs over the next 2 years
64 saves, he averaged 32 saves in the next two years after 26 in Year 1.
15 blown saves, half of his blown saves as a Met came in Year 1
79 save percentage, basically the same rate.

So while he did get better results in his second and third seasons, it wasn't dominance. But with the team never contending for a playoff spot deep into either season, he never had a big moment to redeem himself in the eyes of his critics.

Now we're midway through the 2022 season. Let's look at how Diaz is pitching this season.

2022
29.2 innings
16 saves
3 blown saves
84 save percentage
23 hits
3 home runs
7 earned runs
2.12 ERA
11 walks
57 strikeouts
17.3 K/9
1.14 WHIP

There are a few stats that are just jarring. Diaz is striking out 2 batters per inning, which is a fantastic rate. His ERA has gone way down, and he's giving up a HR every 10 innings instead of every 4. So what has caused the turnaround?

There are two primary aspects of Diaz' pitching to focus on. The first is his first strike percentage is as high as it has ever been. During his best season in 2018, he threw a first pitch strike 67.5% of the time. In 2019, it dropped to 63%, and then down to 60% in each of the next two seasons.

But now in 2022, Diaz is throwing a first pitch strike 70% of the time. And as Diaz is getting ahead in the count early, that makes him just that much more dangerous. He can then work outside the strike zone and get more swings and misses.

The second reason for Diaz' improved performance is the increase of him using his slider. Diaz only throws two pitches, the fastball and the slider. In 2022, for the first time in his career, he is throwing the slider more than he the fastball; 54% of the time, he throws the slider, compared to the fastball, which he is using 46% of the time. And it makes sense, considering that fact that opponents are hitting .171 vs the slider compared to .297 vs the fastball, even though that fastball is reaching up to 103 MPH.

Also, Diaz is getting swings and misses on 51% of sliders thrown. The result? A 48.3% strikeout percentage, compared to 34.6% in 2021.

Is this remarkable improvement to be credited to Diaz himself? Manager Buck Showalter? Pitching coach Jeremy Hefner? All of the above? No matter who gets the credit, the Mets are a far better team in 2022 because Edwin Diaz has established himself as not only of the most capable closers in baseball, but also one of the most reliable. And three years ago, what Mets fan would have thought that was possible?

Jets Black Helmets Review

There are very few topics on which all Jets fans agree. There are a few things we all agree on, such as Joe Klecko belongs in the Hall of Fame, the 2022 draft class has the potential to be one of the best ever, and Adam Gase was a disaster in every way. But with most topics like uniforms, Jets fans tend to be divided. When the team redesigned the logo and uniforms in 2019, everything from the logo to the font to the addition of black became a topic of debate.  It seems as though a lot of people have now warmed up to the black as perhaps the sleakest and most appealing uniforms in the team's arsenal now. But in recent months on Jets social media, there has been a heavy demand for a throwback uniform reminiscent of the 1980's with the Jets airplane logo and the kelly green. So this week, when team owner Woody Johnson teased a helmet reveal on Twitter, it got fans talking. Now that the NFL is allowing alternate helmets for the first time, what would the Jets add? They did not add ...

The best July day in Jets history

 July 27, 2022. The first day of Jets practice. Let's recap what an amazing day this was, actually in my mind, the greatest July day in Jets history.: 1. Mekhi Becton willingly accepted taking the role of right tackle, which in turn allows George Fant to play left tackles, where he is a superior player compared to when he plays right tackle. There was no tackle controversy, like many fans and media thought would happen. No, Coach Robert Saleh addressed it immediately. 2. The kickers! The Jets haven't had a credible placekicker on their roster since Jason Myers. Now they have 2. Veteran free agent Greg Zuerlein and last year's late signing Eddy Piniero have made all 8 kicks they have attempted thus far. 3. Denzel Mims. The most maligned wide receiver in all of football. The second round bust. Well he looks ready to play now. 4 catches on 5 targets, including 2 catches where he had to go up and get the ball. He knows his career is on the line and he playing like it. He may no...

Jets-The Co-Pilots: Jo-Jo Townsell

 The Jets have been blessed to feature some excellent kick returners and punt returners throughout their 60 year history. We know the names: Bruce Harper, Chad Morton, Leon Washington, Brad Smith, Justin Miller, Joe McKnight, Andre Roberts, and now, Braxton Berrios. But one name from the 1980's gets constantly overlooked and his name is Jo-Jo Townsell. Townsell played his college ball at UCLA, along with future Jets teammates Freeman McNeil and Johnny Lynn. Drafted by the Jets in 1983, but decided not to come to New York immediately. Instead, he signed with the Los Angeles Express of the USFL, where he played from 1983 to 1985. Being a Nevada native and California resident, the opportunity to play closer to home appealed to him, but he was also partial to playing in a stadium with natural grass as opposed to artificial turf. After two years in the USFL, Townsell signed with the Jets, where he played his entire NFL career from 1985 to 1990. In that time, he totaled 70 receptions for...
