Secret Substance?

Since when does water or Gatorade help a pitcher effect the movement of his pitches? During the Rockies Phillies game on Wednesday, the Rockies were winning 4 to 2 in the 9th inning when the Rockies closer, Manny Corpas, came in to close the game. But before he did, video caught him doing something very suspicious. The video showed him drinking out of a cup and pouring the substance down his back and chest. While pitching, he kept padding his chest and rubbing his fingers between pitches. http://sportsillustrated.cnn.com/2007/baseball/mlb/specials/playoffs/2007/10/04/bc.bbn.rockies.corpas.ap/index.html Sports Illustrated made it seem like he was using this substance to gain an advantage in the game. Are you kidding me? He drank out of the cup ladies and gentleman. Tell me what substance that would help a pitcher gain an advantage that they would also drink? This just doesn’t make sense at all. These accusations of similar occurrences are getting out of hand. He was probably just overheated and poured some water on himself to cool himself off. Sure sometimes pitches use foreign substances such as Vaseline and pine tar to gain an advantage in games but the fact the he drank the substance that was on his chest makes me think that there is no way that he was using the substance to gain an advantage in the game. Also, it is a common thing for pitchers to grab their jersey and rub their fingers in between pitches. Just because he poured it on his chest, people got suspicious of his actions. I just think that there is no justification to this. He drank out of the cup!
