4. Cleon Jones
The best left fielder in franchise history who caught the final out of the 1969 World Series is Cleon Jones. He played 12 of his 13 years as a Met, playing just 12 games for the White Sox in 1976.
As a Met, Jones slashed .281/.340/.406 with 93 home runs and 521 RBI. When Jones retired, he was the franchise's leader in hits, runs, home runs, RBI, and doubles.
Jones' best season in the majors came in 1969. He slashed .340/.422/.482 with 12 home runs and 75 RBI. The .340 batting average was third in the National League just behind Pete Rose and Roberto Clemente. It was also one of the highest averages for a Met in franchise history. He made his first and only all-star team and helped lead the Mets to a 100 win season.
Jones is a key reason why the Mets beat the Braves in the NLCS, going 6/14, driving in four runs in the three games. In his other chance in the postseason in 1973, Jones hit .292, over 30 points higher than his regular season average.
Having played 12 years in Queens, Jones is in the top 10 in just about every statistical category except for home runs where he ranks in the top 20. Jones was rightfully inducted into the Mets Hall of Fame in 1991 and even if his stats don't blow you away, he'll forever be remembered at least for making the catch to win the World Series.
