For the second time this week, we've seen a relief pitcher ejected for having a so-called "foreign substance" on his arm. This time around it was Marlins manager Dan Jennings who requested Orioles reliever Brian Matusz's arm be checked out. Once the umpires had a look, Matusz was ejected from the game.

The moving pictures:

Matusz took a different route than Brewers reliever Will Smith, who went with the old "everyone does it" excuse (and he's not wrong, by the way). Here's Matusz:

Just as I mentioned earlier this week on the Smith situation, the overwhelming majority of pitchers use some extra stuff to get a better grip. So long as they aren't doctoring the baseball, most opposing players don't have an issue with it -- Braves first baseman Freddie Freeman even went as far as to say he wanted pitchers to have better grips. It is against the rules, though, so a suspension will surely be in order for Matusz.
