WASHINGTON – Jayson Werth is not only a star of the Washington Nats.

He’s also apparently a good-deed doer.

Werth reportedly left a big tip Monday night in Buffalo, where he is currently playing for the Syracuse Chiefs as part of his injury rehab.

Werth reportedly dined at The Black Sheep restaurant on the West Side and ran up a $180.53 bill.

When he was finished, he left a generous $100 tip.

That’s a 55-percent tip.

The waitress — local actress Jessica Wegrzyn — posted the check on Instagram, writing, “Thanks Jayson Werth. You have a real cool beard and you’re real nice and I’ve been told you’re a real good baseball player.”
