What our Post expert thinks about Guardians vs. Rays

The crowd at Progressive Field should be electric.

Not only are the Guardians proving to be a lot to handle for the Rays in the ALCS, grabbing a 2-1 series lead, but they’re getting a home game under the lights Friday night.

We’ll see if Cleveland, not exactly a city known for rewarding its passionate fans, can be up to the task against the Rays.

The Rays are slated to start Nick Martinez, while Cleveland had not announced its starter, as of early Friday morning.
