Mets first baseman Carlos Delgado said he hyperextended his left knee when chasing a foul pop near the first-base stands in the second inning of the Mets' 10-8 win over the Pirates last night.
Delgado stayed in the game but left before the bottom of the eighth.
"It's a little sore," said Delgado, who was unsure if he can play in today's series finale.
