CJ Abrams stayed at Bally's Casino until 8 a.m. before Friday’s game
Abrams went 0-for-3 at the plate with a walk and strikeout that day
He was demoted to Triple-A after the game, but the season is already over
The demotion won't affect Abrams' service time on the Nationals.
He could lose $30,000 of his $752,000 salary for missing the final week
Abrams can file a grievance if he feels the demotion was unfair
He was a key part of the Juan Soto trade two years ago.
Before the All-Star break, Abrams had a .268 average and 15 home runs.
Since the break, Abrams is hitting .203 with just five home runs.
Abrams will enter arbitration as a Super 2 player this offseason.
