Craig Kimbrel had a rough Friday night, giving up two runs in the top of the ninth to give the Minnesota Twins a 3-2 lead. 

Perhaps he should be less slicked down next time he takes the mound?

Kimbrel's Friday night outing may be getting worse extending into Saturday, as Twitter has seemingly uncovered some odd substance on Kimbrel's pitching arm. 

It remains unclear exactly what is coating his arm, but whatever it is, there's a lot of it. 

It was brought up that it could possibly just be sweat, of course, as it was a very hot and humid night in Boston. But the fact that Kimbrel's other arm looks bone dry somewhat puts that theory to rest, especially if he's got much more use for a dry right arm, in theory.

While this certainly is fishy, whatever the substance was obviously didn't help him much, as Kimbrel blew the save and almost cost the Sox the game. Luckily for him, Mookie Betts came through in the bottom of the 10th to win it for the Red Sox, so his night could have been far worse. 

Kimbrel has been great for the  Red Sox, as he has posted an ERA of 2.25 with 32 saves so far this season. But hopefully, for Sox fans, this picture is nothing more than just that. An odd photograph to muse over.
