Before the cat entered play the Cardinals were trailing 5-4 with the bases loaded, but following its departure Yadier Molina blasted a grand slam, helping the Cardinals rally to beat the Kansas City Royals 8-5.
A small gray and black cat ran onto the field during Wednesday night's St. Louis Cardinals game.
But while the blast was consistent with Molina's recent hitting performance, it was the cat, not the catcher, that received the lion's share of the credit.
The Cardinals said the fan claimed the cat was hers and abruptly left with the animal after answering some questions from security.
Catching a few scratches and bites, the crew member carried the cat away from the action.
So, what happened to Rally Cat?
St Louis' Rally Cat walks past Kansas City centrefielder Lorenzo Cain. After leaving the field, everyone wanted to know what he did with the cat.
Merrifield made it 3-0 when he scored on Molina's throwing error in the second. After a series of events, the Cardinals say it is missing.
But the Cardinals (58-56) took advantage of wild Royals starter Trevor Cahill to tie the score before the third inning was over.
Trevor Rosenthal pitched the ninth to garner his ninth save.
Hammel pitched decently Friday night in a 5-2 loss to Seattle, permitting six hits and three runs in 6 1/3 innings, with a walk and three strikeouts. That's when the fan said it was hers, but now she admits she was just trying to give it a home.
Overshadowed in the hubbub surrounding #rallycat is this salient fact about the St. Louis Cardinals: Their offense is functioning at a level many thought it would back in February and March.
