In the wake of the Mitchell Report, several of the 80-plus players implicated in the document have come forward and admitted their use of performance-enhancing drugs. <br><br>The Yankees left-hander was one of the first to admit his guilt, doing so on Saturday, two days after the Mitchell Report said he took HGH in 2002 to help his left elbow heal faster. "If what I did was an error in judgment on my part, I apologize. I accept responsibility for those two days. In 2002, I was injured. I had heard that HGH could promote faster healing for my elbow. I felt an obligation to get back to my team as soon as possible. For this reason, and only this reason, for two days I tried human growth hormone. I was not comfortable with what I was doing, so I stopped. This is it -- two days out of my life; two days out of my entire career. I wasn't looking for an edge. I was looking to heal."
