"We can't look at anybody to help us, we can't look at the schedule, anything like that. I mean, yeah, it's just silly stuff."
Cabrera ranks second in baseball with a .346 batting average. He also has 11 home runs and 60 RBIs.
As a coach with the Yankees from 2004-07, Mattingly got to know Cabrera, who played in New York from 2005-09. Upon hearing of Cabrera's suspension, the Dodgers manager admitted he was "a little bummed out."
"I know Melky's a good kid," Mattingly said. "Honestly, I like him a lot."
Although Mattingly didn't take the opportunity to discuss the division race on Wednesday, he did voice his advocacy for better testing in baseball. He believes the sport can and should do a better job of monitoring its athletes for performance-enhancing substances.
"I've said it before, I'll say it again: Protect players from themselves, protect the fans, protect the organizations," Mattingly said. "The fans, when they see guys play, to me it's about greatness, right? You want to see greatness. You love seeing Matt Kemp and [Andrew] McCutchen and these guys do unbelievable things. But at the end of the day, we want to think they did it because of talent and that they worked really hard to be able to do it. We don't want to think they did it because of any other reason. And so it protects the fans and it protects guys from each other."
Although the current system of drug testing worked in Cabrera's case, Mattingly still thinks it's in need of improvement. He said he's sure there are players out there who are taking performance-enhancing drugs and going unnoticed, which makes him hope that better testing is on the horizon.
"I hope it gets so good that you can't get away with anything, and guys know it," Mattingly said. "That, for me, would be the best."
