Morrison—who had started the play on third—was caught in a rundown, and dove into the base at the same time as Solano’s slide. Solano had began his run from first, and turned the corner believing Morrison would either score or be tagged out at home plate. He was wrong.
The result was an awkward pile of men on third base, and a confused Ian Desmond, who attempted to tag both base runners. Morrison wound up being called for the tag, but had both he and Solano been called out, this play would’ve reached a level of beauty few other baseball moments could match.
