"I didn't eat anything during the day so I just felt tired, without a lot of energy," Hellickson said.
The dehydration was likely why Hellickson felt tightness in his glute muscle as the game went on. He tweaked it further when he tried to hustle off the mound when Gregory Polanco squared to bunt in the sixth inning.
Hellickson said he is hopeful he'll be able to make his next start, and he'll know more after his between-start bullpen session.
"I just got done running," he said before batting practice Tuesday. "Felt OK. Probably get a better idea tomorrow when I get on the mound."
