4. Edgardo Alfonzo
Edgardo Alfonzo had eight of the more under appreciated years in Mets franchise history.
In those eight years, Alfonzo slashed .292/.367/.445 with 120 home runs and 538 RBI. His best season came in 2000 when he made his only all-star appearance and slashed .324/.425/.542 with 25 home runs and 94 RBI. Alfonzo had three seasons in which he received MVP votes, finishing as high as eighth in 1999. That was also the season he won his only Silver Slugger Award.
Alfonzo hit over .300 in four of his eight seasons with the Mets and did a little bit of everything. He was a key piece of the puzzle in the Mets success in the 1999 and 2000 seasons. He had 69 and 67 extra base hits in those seasons respectively, hitting over 40 doubles in both seasons.
Alfonzo is fourth in franchise history in WAR among position players, fifth in batting average, fifth in runs, and fifth in hits. He's in the top 10 in pretty much every major statistical category with the exception of home runs in which he is eleventh.
Fonzie came up with some clutch hits in the postseason as well in his career and ended up in the place he deserved, the Mets Hall of Fame.
