Diaz Optimistic But Rush to Return Remains Uncertain

Mets closer Edwin Diaz hopes to beat typical recovery timeline and pitch again this season after knee surgery.
Diaz's return depends on passing several tests to ensure full recovery and avoid re-injury.
Despite injury in World Baseball Classic, Diaz expresses no regret over representing Puerto Rico.
Diaz receives loud ovation in home opener while continuing rehabilitation and workouts.
Without Diaz, Mets rely on closer David Robertson and key middle relievers to secure late leads.
