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.
