Enrique Hernandez felt his left hamstring tighten Sunday night as he ran through first base on an eighth-inning groundout.
The uncertainty Hernandez felt at that moment remained with him even after Jake Arrieta finished no-hitting the Dodgers in a 2-0 victory for the Chicago Cubs.
"I've never had any hamstring issues before, so I really don't even know what I felt," Hernandez said.
Hernandez thought he was deprived of a deserved infield single in the third inning — the play was scored an error by second baseman Starlin Castro — but the Dodgers utilityman was more concerned about his status for the upcoming three-game series against the San Francisco Giants.
