A ball glove for catching the ball includes a front glove portion, a back glove portion coupled to the front glove portion to define a hand cavity having a thumb stall. The thumb stall has a back side and a palm side. A metacarpal sling extends within the hand cavity. The sling extends from a thumb side of the back glove portion to a pinky side of the back glove portion and continuing along the back side of the thumb stall to the palm side of the thumb stall so as to support the first metacarpal on a person's hand when the person's hand is positioned within the hand cavity.
