Thomas Pannone wasn't expected to be a starter for the Brewers at the outset of the season, but he is another injury in a slew of them to rotation options.

Frankie Montas and left-hander Sean Manaea are both set to start the season on the injured list, but the Mets believe they’re in a good spot.

The veteran southpaw is signing a one-year contract with the Milwaukee Brewers, The Post’s Jon Heyman confirmed Monday. President of baseball operations David Stearns reshaped the Mets’ rotation this offseason by signing Frankie Montas and Clay Holmes to multiyear deals, while re-signing Sean Manaea.
