The 5 most disappointing Mets free agent signings of the last 5 years

4) Dellin Betances

For the better part of his eight-year career with the New York Yankees, Mets fans watch Dellin Betances pitch like one of the best relievers in all of baseball. He was a four-time all-star with the Yankees while posting a 2.36 ERA with them.

Injuries limited the right-hander to just one appearance in 2021, but the Mets still signed him to a one-year deal worth $10.5 million. He was expected to be a key contributor in a revamped bullpen which needed a late-game arm.

The right-hander wound up making 15 appearances for the Mets in the shortened 2020 season, but struggled mightily. He had a 7.71 ERA and had more walks (12) than innings pitched (11.2) and strikeouts (11). Additionally, Betances displayed diminished velocity on the mound. He averaged just 93.6 mph with his fastball in 2020 after consistently hitting the mid/upper 90's as a Yankee.

He made just one appearance in 2021 after accepting his player option before going onto the IL with shoulder issues. He would not make another appearance in the majors. To sum up, this guy who was expected to be a dominant late-game bullpen arm for this team that desperately needed it wound up posting a 7.82 ERA in 16 appearances across two seasons. Not great.

3) Jeurys Familia

Jeurys Familia wound up developing into one of the best closers in Mets history. Low bar, sure, but his seasons in 2015 and 2016 were among the best the franchise has ever had from that position. He tied the Mets club record with 43 saves in 2015, only to break that with 51 in 2016. He had some postseason struggles along the way, but his first stint in Queens was nothing short of great.

After the Mets traded him to the Athletics at the 2018 trade deadline it felt like Familia's tenure with the team was over. It felt like an optimal time to move on from the right-hander as he was set to make a decent amount of money in free agency.

Familia did earn a large chunk of change as he signed a three-year deal to come right back to Queens and was set to make $30 million total. The Mets brought him back but not to close. He'd set up for newly-minted closer Edwin Diaz.

Everyone knows how awful Diaz's 2019 was, but Familia was just as bad if not worse. The right-hander posted a 5.70 ERA in 66 appearances and was practically unusable in any close game. For a Mets team that just missed out on the playoffs that year, all they needed was more reliability from Diaz and Familia to get there.

Familia's next two seasons were better as he settled in nicely into a middle relief role, but that's not what the Mets brought him in to be. His second tenure in Flushing turned out to be a huge disappointment.

2) Max Scherzer

The Mets signed Max Scherzer to be Jacob deGrom's co-ace ahead of the 2022 season. It was Steve Cohen's first massive free agent splash and was seen as a piece that might not only catapult the Mets into postseason contention but completely change the culture. Players of Scherzer's caliber had never seriously considered the Mets in recent years in free agency.

Most of Scherzer's first year with the Mets was a success. He set a career best with a 2.29 ERA in 23 starts and 145.1 innings pitched. had he stayed healthy the entire year he would've been solidly in the NL Cy Young conversation. The way he finished was obviously extremely disappointing. He pitched poorly in a game the Mets had to have in Atlanta which would've won them the division, and then failed miserably in his playoff start against the Padres.

It felt like those late-season struggles found a way to impact him negatively this past season as Scherzer posted a 4.01 ERA in 19 starts for the Mets this season. He missed time due to injury and once again failed in starts that were considered big.

As they did with Verlander, the Mets wound up shipping Scherzer away at the trade deadline to the Rangers in the deal that brought Luisangel Acuna back to Flushing. Acuna being good would help a bit, but Scherzer not even lasting two of the three years he had in his deal is obviously extremely disappointing.

Scherzer wound up missing substantial time due to injury, and failed in games that mattered. He came in with an ironman reputation and as a guy known to be a big-game pitcher. He was neither with New York. There were positives, but the negatives outweighed them in the end.

1) James McCann

After being nothing more than a light-hitting catcher with the Tigers, James McCann turned into one of the best catchers in the American League with the White Sox. He was an all-star in 2019 and had an OPS over 100 points higher in the shortened 2020 season. His bat and glove had improved dramatically with the White Sox making him an appealing free agency target.

At the time McCann was developing into a strong catcher, the best one in all of baseball without a doubt was J.T. Realmuto who fittingly was also a free agent at the end of the 2020 season. The Mets with new owner Steve Cohen had a chance to steal Realmuto away from their division rivals, but did not. They opted to sign McCann before Realmuto agreed to his deal.

The terms of the deal based on the fact that McCann had only been good for a year and a half felt a bit extreme, but Mets fans entered this new beginning with an open mind. After getting no production from catchers in years, it was nice having a guy who could seemingly both hit and defend.

Immediately after signing his four-year deal worth $40 million to join the Mets, McCann turned back to the hitter he was in Detroit. He was one of few Mets able to stay healthy for most of the 2021 season, but had just a .643 OPS that season. He wound up performing even worse offensively in 2022, posting a .538 OPS and losing his starting job to fellow light-hitting catcher Tomas Nido.

In order to get rid of McCann, the Mets had to eat most of his contract and take on nothing in return. The Mets didn't need McCann to be an all-star, but expected him to be a capable hitter and solid defender. The defense was mostly there, but the bat was abysmal while Realmuto continued to be among the best in the game at the position in Philadelphia.
