This is actually great baserunning, but since it’s the Marlins, everyone assumes it’s a goofy blooper.
It happened in Washington last night, when Logan Morrison and Donovan Salano both slid into third base at the same time. Morrison was tagged out, while Salano reached the bag safely.
That’s not something that happens every day. Not even to the Marlins.
Kudos to the umpire for working through a rather confusing situation without embarrassing himself too much.
