Alvarez suffered the injury during the Mets’ win over the Seattle Mariners on Sunday night in Williamsport, Pennsylvania, during MLB’s Little League Classic. The severity of the injury is not yet known, but there is some initial concern Alvarez could be out for the rest of the season.

With Francisco Alvarez out for a minimum of 10 days, the Mets will lean on Luis Torrens and Hayden Senger to pick up some of the slack.

The Mets have another injury concern on their hands as their NL playoff chase picks up following Sunday's 7-3 win over the Mariners.
