Mets catcher Francisco Álvarez, ranked as the No. 1 prospect in baseball by MLB Pipeline, had surgery to address cartilage damage in his right ankle on Tuesday.

The injury, which nearly ended his season in September, stems from the loose body in his ankle. The Mets expect him to be ready for Spring Training.

Álvarez debuted at the end of September amid New York's playoff run.

The 20-year-old just wrapped up his first season in the upper Minors, slashing .260/.374/.511 with 27 home runs over 112 games split between Double-A Binghamton and Triple-A Syracuse.

Álvarez had two hits, including a home run, in 12 at-bats for the Mets during the regular season.
