Mass confusion broke out at Wrigley Field Friday afternoon.
Leading off the top of the second inning, Reds right fielder Mason Williams smoked an Alec Mills offering out to left-center.
Albert Almora Jr. tracked the ball all the way to the ivy, but that quirky basket hanging off the bleachers got in the way.
After presumably going over the fence, the ball bounced up and back onto the field of play, where Kyle Schwarber caught it on a fly.
Williams was unsure what to do, so he hesitated around second base, then continued his home run trot. Schwarber threw the ball back in toward second and waved his arms frantically to indicate the ball did not go over the fence. Meanwhile, Almora sat on the ground after tangling with the brick wall behind the vines.
The Cubs immediately challenged the play and the end result was one of the wackiest moments in the 2018 MLB season:
Yes, that's right, the ball bounced off the TOP of the basket. Thus, it was not a home run.
But since it struck something else, it wasn't an out either when Schwarber caught the ball.

Williams was forced to return to second base. He later scored on a Phillip Ervin double three pitches later, but it was still such an odd sight.
The ball itself is only a hit 30 percent of the time, coming off Williams' bat at 95.5 mph.
But the 9 mph wind blowing out at Wrigley Field helped combine for one of the most improbable moments in the century-plus year history of the ballpark.
