Andy Roddick's biting four-word phrase slams Nick Kyrgios

Did he or didn't he? That seems to be the question surrounding Jannik Sinner and his positive tests for a banned substance called Clobestol. Twice in March, Sinner was positive for the substance in his system. He was provisionally suspended but then cleared of any further discipline.

Sinner has maintained he did not intentionally take the steroid. Clobestol is supposed to help those building muscle mass. As a tennis player, Sinner likely is never going to look like a bodybuilder because he plays an endurance sport that works better for someone who is quick rather than someone who resembles a young Arnold Schwarzenegger.

That doesn't mean the mass that Sinner does add won't help him hit with more pace.

Andy Roddick sends a biting correction to Nick Kyrgios on social media

Still, after a review by the International Tennis Integrity Agency, the Italian was deemed not guilty of doing anything on purpose as far as taking the banned substance. The ITIA handled the Simona Halep situation differently as she was suspended nearly immediately, and this is where some have issues with Sinner not being banned.

One of those persons is tennis commentator (and sometimes player) Nick Kyrgios. The Australian thinks Sinner should have been suspended after the positive tests and then once his innocence was proven he might then have his ban reduced. This is what happened with Halep.

Kyrgios seems to be speaking a bit out of the knowledge of how long Clobestol stays in one's system, though. In a social media post, Kyrgios said that the substance should be out of one's system in "hours." The truth appears to be that the substance could be detectable for up to 13 days.

Worse, when an X user responded to Kyrgios post with a question of how Kyrgios would know how long Clobestol stays in the system, the Australian responded with, "Research. Dumb ass." The irony is that Kyrgios was the one who was being ignorant about the substance and a potential positive test.

Andy Roddick took umbrage with Kyrgios's remarks. Of course, Roddick is not one to not speak his mind freely. After all, he has an excellent podcast called Served with Andy Roddick where he discusses all manner of subjects.

Roddick responded to Kyrgios with a four-word phrase, "Dumbass is one word." The truth was in the biting dig from Roddick. Without calling Kyrgios "dumb," he pointed out that not only was the Australian wrong about his take on Clobestol but Kyrgios even misspelled the insult he directed at the X user. Maybe Nick Kyrgios is the one who needs to do better research.
