Nationals left-hander Gio Gonzalez was one of many players named in a recent report linking him to the South Florida clinic Biogenesis and performance-enhancing drugs. MLB drug-tested the southpaw two days after the report surfaced, and the results are in:

Gonzalez, 27, has strongly denied using any banned substances or meeting Anthony Bosch, the chief at Biogenesis. A recent ESPN report indicated that while Gonzalez's father had ties to the clinic, the left-hander never received any performance-enhancers.
