Rick Porcello has some strong opinions about Major League Baseball's performance-enhancing drug policies.

The collective bargaining agreement expires at the end of this year, so there is a chance that changes can be made.

"It better be realistic because obviously what's going on right now isn't getting it done," Porcello said.

Justin Verlander, a former teammate of Porcello's, recently came out against rules allowing suspended players to play during the appeal process.

"I have an absolute problem with them playing under the appeal or due process because you're taking a guy who has tested positive for something," the Boston Red Sox right-hander said. "Clearly playing with that advantage at that particular time, and he's impacting games. The whole idea behind the system is to prevent guys who tested positive have an unfair advantage in a game, then why would they be allowed to play during the appeal process when they clearly have that in their system. To me, that doesn't make sense.

"You break down the season and you look at all the years it comes down to one or two games, and you have a player out there playing with that advantage, just because it's in April or May and not late in the year, doesn't mean that one game isn't important. If he goes out there and outperforms the other team or does something huge in that game to win and your club gets edged out by a game at the end of the season, that guy who is playing with the banned substance in his system had a direct impact on his team and the season. I don't think that’s right. It's not the same as appealing a suspension for getting thrown out of a game or something like that. We're talking about two completely different things."
