The blast was estimated to have traveled 470 feet.
"Approximately," Goldschmidt said when asked if he saw how far his ball went. "But I didn't go watch it or anything like that."
The longest home run in Chase Field history was a 504-foot blast by Adam Dunn in 2008. Goldschmidt's homer tied Mark Reynolds for the 10th-longest hit by a D-backs player at Chase Field.
Goldschmidt was asked if that's the furthest he's ever hit a ball.
"That I can remember," he said with a shrug. "It generally counts as one, but it's better than nothing."
Center fielder A.J. Pollock said he remembered Goldschmidt hitting one that "easily went 30 feet further" than Wednesday's shot when the pair played for Double-A Mobile.
