Confusion reigned when Yan Gomes' fly ball bounced off the Minute Maid Park roof

Baseballs can't just disappear. That's not how physics work in our reality. And yet, that seemed to happen during Saturday's Indians-Astros game at Minute Maid Park.
Yan Gomes hit a towering shot to left field off Astros pitcher Mike Fiers in the second inning. Norichika Aoki raced back to the wall ... and then ... poof. He had no idea where the ball was. The broadcast crew had no idea where the ball was. Gomes himself had no idea where the ball was. 

Lonnie Chisenhall and José Altuve played a game of "Did you see that?" while A.J. Hinch clearly wondered "How does a baseball just disappear? 

Even the broadcast crew was confused, thinking that the ball had somehow hit the wall and bounced back to the infield when Carlos Correa snatched it. 
 "I was just looking at Aoki and waiting for him to catch it and all of a sudden he goes like [puts arms out] 'Where's the ball at?'" Correa said after the game. "When I looked up, the ball is dropping a couple of feet behind me, so I had to go get it."
While Gomes wound up on first base with a single, no one thought that was the result off the bat. "I think it was going foul actually," Fiers said. "Gomes was mad at what he did because he pulled it and hit it straight up in the air and it ended up being a single for him."
Was this like the rare phenemona when frogs are reported to fall from the sky? Had Gomes blasted it into a vortex? Sadly, it had a much more mundane explanation: the ball hit off a girder inside the dome.
"It's a dome, things like that are going to happen," the catcher said. "I hit it, it hit the roof and it came back fair so I just ran. Nothing to it. I figured it's happen a bunch of times."
Though balls occasionally bounce off the roof in foul territory, it's much more rare for it to happen to a fair ball. 
"It's not normal for it to fall fair," Hinch said. "Hit fair, fall fair, which is the ground rule."
