D-backs manager Kirk Gibson did not ask Goldschmidt if he wanted a day off, he simply told him that's the way it was going to be.
"He's getting an off-day," Gibson said. "I've been thinking about it, been talking about it. Just watching him and seeing some certain things. Just think it's time."
Shortstop Cliff Pennington decided to have some fun with the news, giving Goldschmidt a bottle of vitamins. The bottle's label was covered with athletic tape, and on it, Pennington wrote "Harvey-itis."
Below that, Pennington scribbled, "Symptoms: excess velocity, sharp curves and disappearing changeups."
"They're giving me a hard time," Goldschmidt said. "It's all in good fun."
Goldschmidt planned to take it a little easy pregame, but he also said he was going to be ready if needed during the game.
"You just try and just relax a little bit and enjoy it at least for the first few innings, and then get ready if you have to come into the game at the end," he said.
Goldschmidt has not faced Harvey before and had been looking forward to the challenge.
"I think as a hitter, you definitely want to test yourself against the best," Goldschmidt said. "And he's one of the best, if not the best, in the National League right now."
