Is the World Series going to turn into Shinguard-Gate?

A mini-controversy appears to be brewing after Fox cameras caught Royals catcher Salvador Perez with some kind of brown substance on his shinguards.

Perez didn’t speak to reporters after the game and manager Ned Yost correctly pointed out that there is nothing wrong with the catcher — or any position player — having the substance, believed to be pine tar, there.

“It’s not illegal,” Yost said. “I don’t know what it was. It was brown. It’s not illegal for a catcher to have it on his shinguard. It’s illegal for a pitcher.”

ESPN analyst and Red Sox great Curt Schilling had an interesting take.

Mets captain David Wright laughed when asked about it, and said he didn’t have any thoughts on the mystery substance. But this probably is not the last we hear about Perez’s shinguards in this series.
