Santana received an 80-game suspension Monday after testing positive for the performance-enhancing drug Boldenone, Mark Feinsand of MLB.com reports.
Santana hit .283/.324/.534 in a breakout campaign in 2019, but he's struggled to a .170/.247/.322 line in 53 games since then while battling injuries. Those struggles alone may explain why the 31-year-old is still a free agent, but it will now be even harder for him to find a deal.
