BOSTONRed Sox manager Bobby Valentine was asked his reaction to the news that As right-hander Bartolo Colon has been suspended 50 games for testing positive for testosterone, a performance-enhancing substance in violation of Major League Baseball's Joint Drug Prevention and Treatment Program.I just wish we got that loss back that he pitched against us, Valentine said.He was referring to the 3-2 loss on July 3 in Oakland.Colon and Giants outfielder Melky Cabrera are the two most recent players who have been found to be in violation of MLBs policies. Valentine was asked if he thought the teams records were tainted because of that.I wouldnt, he said.It seems that whatever were doing were doing properly , he said. And just like the Olympics have their issues and their system that seems to have worked well over the years, better and better, theres always some things that fall through the cracks and some people who think that theyre slippery enough to do that.It is difficult, though, for a manager to know what each player on his roster is doing.I dont think he can be responsible for what guys are doing personally, Valentine said. Its tough. I think its very tough. I managed in the 80s and 90s and probably my biggest regret in life is I didn't know more and figure it out better. Its a regret. But I dont know how I could have.Asked if he thought some managers looked the other way, Valentine replied:Probably. Im not sure. I dont think its in our job description to police things. Not only drugs and steroids. We try to get people to know the difference between right and wrong. We try to surround ourselves with those people who do that. After that, I think its difficult to try to police it.
