Hernandez, 71, lost his focus on the match as the cameras cut away to a pickleball match in Florida during a break in the Mets action.
KEITH HERNANDEZ was "distracted" in the Mets booth after being shown a bikini-clad pickleball player.
A second wrote: "The day Keith Hernandez retires from the broadcast booth will be a National Day of Mourning.".
The MLB legend and broadcaster was calling New York's spring training match against the Astros when he lost his concentration.
The match featured a man and a woman playing the racket sport.
