"During the course of preparing for my successful appeal last year, my attorneys, who were previously familiar with Tony Bosch, used him as a consultant. More specifically, he answered questions about T/E ratio and possibilities of tampering with samples," Braun said.
The T/E ratio is a comparison of the levels of testosterone to epitestosterone.
Braun led the NL in homers (41), runs (108) and slugging percentage (.595) last season while batting .319 with 112 RBIs and 30 stolen bases. He finished second to San Francisco catcher Buster Posey in MVP balloting."
Cervelli, who spent nearly all of last season in Triple-A, posted a statement on Twitter later Tuesday night.
"Following my foot injury in March 2011, I consulted with a number of experts, including BioGenesis Clinic, for (cont)," Cervelli posted, "(cont)legal ways to aid my rehab and recovery. I purchased supplements that I am certain were not prohibited by Major League Baseball."
