Sabathia was seen stuffing what appeared to be a heating pad into his jacket while in the dugout.
Speculation immediately surfaced that he had tweaked a muscle somewhere in his midsection, and was attempting to stimulate blood flow to the area through direct heat.
Had Sabathia injured his rib cage or oblique muscles, it could result in a lengthy stint on the disabled list.
The fact that it was not an exceptionally cold day fueled speculation, especially when taking into account Sabathia's time spent in Cleveland's frigid Aprils.
Fears were quieted following Sabathia's explanation of desiring extra heat in order to keep his core loose and warm.
The only thing that could derail the Yankees season after Opening Day would be losing a member of their wealthy rotation for any extended period of time.
Manger Joe Girardi and his team can breathe a collective sigh of relief, as they do not need to entertain the possiblity or fear of that happening quite yet.
After all, A.J. Burnett does not pitch until Thursday (just a little DL joke that I could not resist).
