In May 2018, Gomez said in multiple interviews that he did not believe MLB's drug testing was random and that he believed the league targets older players and Latin players. He claimed to have been tested six or seven times within the season's first two months. As translated by journalist Hector Gomez, Carlos Gomez said in Spanish: "Until they prove to me that it is random, I will not believe it. Because for me, it's not random...I have the greatest luck on my team, because they test me more than everyone else. I arrived now, three days after coming from the disabled list, and they are already testing me again."
