"I ate something, drank a lot of water, and I feel great right now," Gonzalez said. "About 30 minutes after I came out of the game, that's when I started catching up."
Gonzalez was fine in the first inning during his RBI double -- his third extra-base hit in as many games. After walking in the third, he rounded second on Troy Tulowitzki's deep fly ball that was caught at the warning track, and he did not make it back to first on time to avoid being doubled.
At that point, he began to feel ill, and it lingered when he struck out in both the fourth and sixth innings.
"I thought it was one of those things that happens and just goes away," Gonzalez said. "After my third [plate] appearance, I was sweating and shaking. I didn't know what was happening. It never got better. I told the staff that I wasn't feeling very well. I came up to hit again and was feeling the same way, so they just took me out."
