The Mets recalled Zuber from Triple-A Syracuse on Saturday, Mike Puma of the New York Post reports.
Zuber has been in the minors all season, putting up a 6.08 ERA and 1.64 WHIP through 23.2 innings. Despite his poor minor-league performance, the Mets will rely on him to make up for the departures of Blade Tidwell and Justin Garza, both of whom were optioned to Syracuse on Saturday.
