Derek Jeter's on full-time daddy duty, but that didn't stop him from catching some playoff basketball, pulling up to Game 4 of the Heat vs. Celtics series in Miami with his wife Hannah ... just 18 days after their son was born!
And, HJ looks amazing!
Cameras captured The Captain throughout the evening ... as he chatted with his wife as the Celtics looked to avoid the sweep at the hands of Jimmy Butler's Heat squad.
