Regular season
1984 got off to an embarrassing start for GM Frank Cashen and the Mets before the season even began. Believing that it was unnecessary to protect a high-salaried, 39-year-old pitcher, the Mets left Tom Seaver unprotected. In a move that stunned the Mets, on January 20 Seaver was claimed in a free-agent compensation draft by the Chicago White Sox.

This left opening day duties to Mike Torrez. Torrez lasted only 1.1 innings against the Cincinnati Reds at Riverfront Stadium, giving up six earned runs, and giving the Mets their first opening day loss since 1974. Davey Johnson's team did, however, come back to win the next six in a row, including Dwight Gooden's Major League Baseball debut on April 7. Johnson also helped bring the Mets back in contention, producing their first winning season since 1976. Off-season acquisition Sid Fernandez made his debut with the Mets on July 16, going seven innings against the Houston Astros at the Astrodome, and earning the victory.
