Former Tennis pro James Blake on Wednesday criticized Mayor Bill de Blasio for leaving him in the dark about an NYPD departmental trial regarding his false arrest — and reiterated that the officer involved should be fired.

“It’s disappointing that the de Blasio administration and NYPD failed to notify me that James Frascatore was in a departmental trial yesterday related to the incident involving me in 2015,” Blake said in a statement.

“But the lack of real punishment for Frascatore is the bigger travesty.”

NYPD Officer Frascatore, who is white, slammed Blake to the ground in a case of mistaken identity outside of the Grand Hyatt hotel in Midtown on Sept. 9, 2015.

Blake was unhappy with the lack of transparency over his departmental trial and said it would impede information from getting to the public.

“I would expect the common courtesy of a notification from a city that claims to be improving the transparency of how its police department operates,” he said.

“I urge the de Blasio administration to ensure that the disciplinary outcome in Frascatore’s case is shared with the public and with me, and not shrouded in secrecy.”

Blake also blasted Frascatore — who he said should be fired — for claiming during the departmental trial that Blake turned the incident into a “racial issue.”

“Frascatore employment with the NYPD should be terminated and he should not be allowed to sully the badge that so many other good cops wear with honor,” he continued.

“The baseless claims made by Frascatore against me in the departmental trial are a desperate attempt to justify his unjustifiable and abusive use of force against me back in 2015.”
