Number 13 is one of the more stacked numbers in terms of quality of New York Mets players who have worn it. Right now Luis Guillorme is wearing it, and he's a key bench piece on the Mets. Asdrubal Cabrera wore it for a couple of years, so did Jerry Blevins. BIlly Wagner was dominant as a Met and he wore number 13 as well.
The best Met to have worn number 13 is Edgardo Alfonzo.
In Alfonzo's eight seasons with the Mets he wore number 13 the entire time. He split time between second and third base and was very productive at both spots.
Edgardo Alfonzo is the best Mets player to wear number 13
Fonzie slashed .292/.367/.445 for the Mets with 120 home runs and 538 RBI. When he first came up in the 1995 season, he wasn't very good at the plate posting a 82 OPS+ and hitting just four home runs in 335 at bats. As the years went by, he progressed into a future all-star and a key piece to a team that won the 2000 National League Pennant.
Alfonzo's best season came in that 2000 season when he slashed .324/.425/.542 with 25 home runs and 94 RBI. He tacked on 40 doubles and 109 runs hitting right in front of Mike Piazza most of the time. He made the only all-star team of his career that season and finished in the top 15 in the National League MVP balloting for the third time.
Alfonzo also had an above average glove, posting a 2.1 dWAR season playing third base mostly in 1997 which is tied for tenth highest in a single season in Mets history.
Alfonzo ranks fourth in bWAR among position players, fifth in batting average, runs, and hits. He's in the top 10 of virtually every important statistical category with the exception of home runs in which he was just two shy of tying Kevin McReynolds for tenth in Mets history.
Fonzie wore number 13 longer than any Met and was without a doubt the best to ever wear the lucky number while also being one of the greatest infielders in Mets history.
