  • A new book, I’m Keith Hernandez, was released on May 15, 2018. The book covers his life through early in the 1980 season, and, depending on sales, may lead to a follow-up with me picking up the narrative from that point.

Mets

  • On 15 June 1983, the Cardinals traded Hernandez to the Mets, massively changing the course of Hernandez’s life as well as the team’s history for the better. Even though he initially hated it.
  • “Now I had a new challenge with the last-place Mets,” Hernandez said. “That opened up a whole new motivation for me.” Hernandez briefly considered retiring.
  • “That’s acting on emotion. I’m an emotional guy,” Hernandez said. “I’m kind of a compulsive, impulsive personality, which I’ve learned to keep a tighter rein on. But it’s who I am. I was purely reacting on emotion, to hurt, to the pain of being traded, going to the Mets, which were a last-place team. It was just a very unsettling second half of the season in ‘83. It was just a tough year for me.”
