It's not the heat...

...it's the stupidity.

NEW YORK (AP) -- Kevin Brown's frustrating season finally reached a boiling point, and now his hot temper could cost the New York Yankees at the most important time.

Brown broke his non-pitching hand when he punched a wall in the clubhouse Friday night during a 3-1 loss to the Baltimore Orioles that cut New York's lead in the AL East to just 2 1/2 games over Boston.

"Stupidity," Brown said, choosing his words carefully.
