"This is not the Minor Leagues. This is a big league camp," Guillen said. "I got that from Bobby Cox. The drill we have to do, we have to do it because it's a reminder. But we're not coming here to teach.
"You should know what to do, where's your position, where you're going to be and we'll deal with that. You have to do what you have to do even if you don't like it. I would rather have guys hit and take ground balls and do situational things."
Guillen understands fundamental workouts such as Friday's won't guarantee a lack of miscues during the regular season.
"In 162 games, you will make mistakes. Like the rundown plays," Guillen said. "If you don't know how to do that, come on. A lot of teams don't do it the right way.
"During the season people think we don't practice. Yes, we do. Everybody practices everything. Some people put in 10 hours, some people put in two, but they all work."
