Moore has said he would love to be considered as a replacement for one of those pitchers. And Maddon would love to see it happen.
"I am hopeful," Maddon said. "I believe it is something that can happen, but I have not heard from anybody yet. There's three guys who are pitching on Sunday who have to be bumped? I'd have to believe Matt's got a pretty good shot under those circumstances. And that would be great."
Moore's next scheduled start is Thursday, which would put him on perfect rest to appear in the game.
The three All-Stars scheduled to pitch on Sunday are: Seattle's Hisashi Iwakuma, Detroit's Justin Verlander and Oakland's Bartolo Colon.
