There may have been a chill in the air but Rosary's bats were on fire and so was Royals' pitcher Elayne Young.
The junior righthander fired a two-hitter and was backed by an 11-hit attack as Rosary won an 8-2 Suburban Christian Conference battle with neighborhood rival Aurora Central.
The Chargers (10-9) struggled defensively, committing five errors.
"Our bats are coming alive," Rosary assistant coach Rob Henderson said. "It's been a bit of a struggle, so we'll take the solid hits and putting eight runs on the board."
Rosary, 5-11 and 5-4 in the league, was playing without head coach John Kazmierczak, who was out of state attending a funeral.
"Elayne was solid, as always," Henderson said.
Young struck out nine batters and walked one. Both runs she gave up were unearned, courtesy of Rosary's two errors.
Mary Willeman singled in the first, moved to second on a passed ball and scored on an infield throwing error to stake ACC pitcher Paige Miller to an early lead.
The Royals answered in the second with four unearned runs in the second then added solo tallies in each of the next three innings.
"I don't knnow what to say," said Charger coach Tom Babyar. "We were horrible defensively. We put our pitcher in a hole, giving them four runs in the second.
"They should have had no runs. Then you can play the game differently. It was just ugly and kind of embarrassing but it is what it is. You have to learn from it and go on."
Senior catcher Lauren Murray had a pair of doubles to drive in three runs and senior first baseman Sam Phelps had three hits, including a double, and drove in one run. Junior third baseman Madison McDonald had a pair of singles and drove in two runs.
"Those two (doubles) were on pitches that kinda looked like beach balls," Murray said. "They were right down the middle. I just sat back and waited for it.
"This is a confidence booster. We either hit a lot or not at all."
Cori Dahl had ACC's other hit and Young (4-4) retired the last 10 batters in a row.
