NEW HAVEN, Conn. — A former ESPN production assistant whose affair with broadcaster Steve Phillips led to their firings has filed a defamation lawsuit against the sports network.

The suit by Brooke Hundley, 22, filed Tuesday in Stamford Superior Court, says ESPN defamed her by firing her based on false statements by Phillips and by claiming she had not fully cooperated with its investigation.

ESPN said Hundley’s claims are without merit. The Bristol-based network said its investigation found Hundley’s characterization of the affair inconsistent.

Phillips acknowledged his relationship with Hundley. His representative, Steve Lefkowitz, said the former Met general manager was focused on getting his life and career back on track.

Phillips and Hundley were fired in October.
