6. Kevin McReynolds
One of the more interesting trades the Mets have made came after winning the 1986 World Series. They traded Kevin MItchell, who famously scored the game tying run in Game 6 of the World Series and was coming off of a very solid first full season in the majors, along with some other pieces in exchange for Kevin McReynolds.
The Mets were getting a really solid player who was just coming off of his best season in 1986. He followed that up with even better seasons in Queens. As a Met, McReynolds slashed .272/.331/.460 with 122 home runs and 456 RBI in 787 games.
McReynolds wasn't the flashiest Met, which on a roster including guys like Doc Gooden and Darryl Strawberry that would've been hard to do, but he was one of if not the most consistent Met from 1987-1990. He was a guy you could guarantee would hit .270 with 20+ bombs and 80+ RBI. He even stole some bases, stealing at least 14 from 1987-1989.
While he was great with the bat, he was just as great in left field. He led the league in outfield assists from 1988-1990 and was extremely reliable tracking down anything hit his way.
In his lone postseason as a Met, McReynolds hit two home runs in a hard fought seven game series loss to the Dodgers in the NLCS with an .848 OPS.
McReynolds is tenth in home runs and 11th in RBI in Mets franchise history and is a guy with a Mets Hall of Fame case for sure. He's without a doubt a top left fielder in the history of the Mets.
