EXCLUSIVE

She's a regular Justin Purrlander ... or Clayton Furrshaw ... 'cause Hero Cat threw out the first pitch at a minor league baseball game tonight -- AND CRUSHED IT!!

TMZ Sports has obtained pics of Hero Cat and Jeremy (pictured below) -- the little boy she saved from that vicious dog earlier this month -- taking the mound together at the Bakersfield Blaze game (the Class-A affiliate of the Cincinnati Reds).

Of course, the now famous cat-beats-dog incident took place only miles from the stadium -- and the Blaze reached out to honor their hometown hero.

We're told the crowd cheered like crazy for the pair -- and after the pitch, they stayed to take in the rest of the game from seats right near the CATcher.

Ha.
