2) NY Mets outfielder Yoenis Cespedes - 4 years/$110 million dollars
When the Mets traded for Yoenis Cespedes he took the New York baseball world by storm. Who can forget the absurd second half he had in 2015 once the Mets acquired him. He practically willed the Mets to a division title. He then followed that up with a monster year in 2016 and willed them back to the postseason despite half of their roster being on the IL.
The Mets rewarded Cespedes with a lucrative four-year contract worth $110 million dollars after the 2016 season. The contract at the time was the highest AAV ever for an outfielder and tied the highest AAV for a position player free agent signing. it's safe to say that contract didn't age anything close to the way the Mets expected it to.
Cespedes hit the ball extremely well in 2017 but he played in only 81 games. This was followed by 38 games played in 2018, zero in 2019, and eight in 2020 before he opted out of the shortened season.
Cespedes dealt with numerous injuries and had his own troubles off the field like when he fractured his ankle running away from a wild boar or when he disappeared from the team right before he opted out in 2020.
I'll always remember 2015 and 2016 but after signing his big extension, Cespedes was rarely seen on the field. Hopefully we'll see him at an Old Timer's Day soon.
