In a statement, Santana admitted to unknowingly using the drug back in his native country of the Dominican Republic:

I serve as a role model for many kids in my home country who dream of playing at the highest level. I would never put baseball, my family, or my country in a position where its integrity is jeopardized. I preach hard work, and don’t believe in short cuts. I am very disappointed that I tested positive for a performance enhancing drug. I am frustrated that I can’t pinpoint how the substance in question entered my body.

I would never knowingly take anything illegal to enhance my performance. What I can guarantee is I never knowingly took anything illegal to enhance my performance. That’s just not me, never has ben and never will.

Moving forward, I need to be more careful on what I consume in my home country, I will be more vigilant of medications I take so that I don’t commit another mistake. Having said that, I believe it is best to move forward and accept the punishment that has been negotiated by MLB and MLBPA for my positive PED test.

He also apologized:

My deepest apologies to my family, fans, colleagues, teammates and my current employer the Minnesota Twins. All I can do now is continue to work hard, and when the suspension is up, come back to doing what I love.
