A's Star Chris Bassitt Returns To Mound 1 Month After Breaking Face

Incredible scene on the baseball diamond in Oakland Thursday ... Chris Bassitt returned to the mound just a few weeks after a comebacker broke his face -- and he dominated!!

The A's star pitcher -- who was seriously injured during a game against the White Sox on Aug. 17 -- took the hill for the first time since the freak play ... and threw 3 scoreless innings against the Mariners.

He also struck out four and only gave up one hit ... and the crowd in Oakland was THRILLED to see it all.

Of course, it was hard to fathom seeing this scene just a month ago ... 'cause Bassitt was hit so hard by a line drive, he needed a plate put into his face to stabilize the damage.

The 32-year-old, though, worked his ass off to come back to give Oakland just what it needed ... and, now, the A's currently lead 4-1 in the fourth inning.
