The Illini, meanwhile, lead the entire NCAA in slugging percentage and dominate in home runs (71, six more than second place). They also rank amongst the nation's elite in runs scored (6.8 per game) and batting average.
Sullivan attributed her squad's offensive outpouring to experience and increased discipline at the plate -- the Illini lead the Big Ten in walks.
"We're dedicated. We work day in and day out on making ourselves better complete players," Sullivan said. "Probably, most importantly has been our confidence at the pate. Our confidence grew the most and now we expect to hit, but you're only as good as your next game so we can't sit on our stats."
Illinois' dominance in the Big Ten is even more impressive than its national ranking. The Illini lead the conference in eight offensive categories and boast four of the top-10 players in home runs, RBI, total bases, runs and slugging percentage.
With the mind-boggling numbers being posted by the Illinois bats and the Iowa pitchers, opponents can become intimidated. But, Penn State pitcher/utility player Jenn Reynolds said the Lions are up for the challenge.
"We have been hitting the ball really well, so we're ready to go out and battle against Iowa's pitching," she said. "Against Illinois, we [pitchers] just obviously need to hit our spots and pitch with control. And we have a great defense, too, so we're ready for both challenges this weekend."
