Selected by the Mets in the 5th round of the 1971 free agent draft, catcher Francisco Estrada spent the 1971 season in the minors before being recalled to the big club in September. He would make his Major League debut on September 14 replacing Jerry Grote in the 5th inning against the Montreal Expos. Estrada would single in his first big league at bat and finished the game 1-2. It would be his only appearance with the Mets, following the season, he was part of one of the most infamous trades in franchise history. He was traded to the California Angels along with Leroy Stanton, Don Rose and Nolan Ryan in exchange for third baseman Jim Fregosi.
His one appearance with the Mets in 1971 would be his only major league appearance.
While with the Mets Estrada wore number 5.
