Umpires (and broadcasters) calling games at Camden Yards this season will have a whole host of new rules to memorize, thanks to the new (er) left-field wall at Oriole Park.

Despite a challenge from the Rays, officials determined there was no fan interference on this catch by Zack Hample.

The ball appeared to hit the wall near the yellow home-run strip, making it unclear whether it went out. As Ohtani jogged to second base, an umpire signaled home run, but the play would be reviewed.
