Later, in the eighth inning of the Royals' 8-4 loss, Crow looked perfectly healthy as he retired all three batters he faced.
Even though he pitched Sunday for the Royals, he wasn't feeling his best before joining Detroit pitcher Justin Verlander's group that evening on a private jet to the 82nd Midsummer Classic.
"I wasn't feeling well Sunday before I went. I just thought it was allergies or something, but it just kept getting worse," Crow said. "Monday was probably the worst it was. Tuesday it started to get better, but I felt pretty bad. The doctor said it was probably strep throat, but it was the worst time that it came."
Crow did not pitch for the American League during its 5-1 loss to the National League, but it wasn't his illness that kept him out of the game.
"They told me before [the game started] I was only going to pitch if it went extra innings or somebody reached their pitch count or something like that," Crow said. "They had that planned out beforehand."
Although Crow didn't get in the game, he had a good time visiting with his fellow AL pitchers in the bullpen.
"All those guys are pretty cool -- [Brandon] League, [Jose] Valverde, [Jordan] Walden, [Chris] Perez. They were all great guys and it was fun to get to talk to them," he said.
Crow felt well enough to attend almost all the activities except for the postgame parties.
"I think the adrenaline kicked in, because afterward when I was back in the hotel after the game, I kind of felt bad," he said. "During the Home Run Derby on Monday I felt fine, but I think the atmosphere and everything made me feel a lot better."
His parents, brother, Travis, and sister, Jennifer, were among those who traveled to Phoenix for the game.
"I had an awesome time. It was a great experience," Crow said. "Hopefully I can go back again sometime and get to re-live it again. ... Maybe next year at home. But we'll see."
