"He's had a huge impact against us," Gibson said. "My understanding is he admitted to taking it and knew what he took and that's just not right. If you do something like that, in my mind, it should be much more severe."
Gibson said he would be in favor of a one-year suspension for those who test positive a first time and a lifetime ban after a second positive test.
"Part of me says that, enough already," Gibson said. "We've made a commitment to stopping that kind of activity and we still from time to time find that people are still trying to fool the system. Maybe they should consider a much stricter penalty. It's just bull. I would say the majority of the people who are in this game care about the integrity of the game. We're all committed to that and cleaning it up. Obviously there's not a big enough deterrent if it continues so I think the penalty needs to be much more severe."
Gibson alluded to the fact that this is not the first time the D-backs have been stung by someone who has tested positive for performance-enhancing substances. He cited 2008 when the D-backs were overtaken by the Dodgers and lost the NL West by two games after the Dodgers acquired Manny Ramirez.
During Spring Training the following year, Ramirez tested positive for a banned substance and received a 50-game suspension.
"Go back to 2008 and now we have the Manny thing," Gibson said. "Huge impact."
Left unsaid was the fact that Brewers outfielder Ryan Braun tested positive for a banned substance during last year's NL Division Series against the D-backs. Braun hit .500 with four doubles, a homer and four RBIs in the series, which the Brewers won three games to one.
Braun's suspension was overturned on appeal.
"It's disappointing," D-backs outfielder Jason Kubel said of Cabrera. "It's just unfortunate that there are guys still doing this."
Catcher Miguel Montero expressed similar sentiments.
"I'm just disappointed," Montero said. "I think he's a good-enough player that he doesn't need that stuff. I don't think he needs it. I don't know why he used it. I know the guy. I know he's a heck of a player. To see him going down this way is a disappointment."
