Goldschmidt, who entered the game hitting .237 with two home runs and 15 RBIs, has been fine-tuning his mechanics with hitting drills on a tee this week.
He said his confidence is not one of the problems.
"You just have to keep battling through it," Goldschmidt said. "I've been getting some good pitches to hit but maybe I'm fouling them or swinging and missing too many of them. But for the most part, I am swinging at good pitches and taking a good approach."
He struck out looking in his first at-bat Sunday.
