Rachel Loube was able to crack a smile, but the Calvert senior guard wasn’t about to sugarcoat her team’s performance Friday.

The No. 9 Cavaliers played what Coach Frank Moore said was his team’s worst game in two seasons, but the defending Maryland 2A champions still beat Patterson Mill, 42-31, in a state semifinal at UMBC’s RAC Arena.

Calvert will play Century (24-2) in the 2A final on Saturday at 1 p.m. at UMBC.

“I don’t know what it was, but each one of us started out slow,” Loube said. “We couldn’t catch the ball, couldn’t pass the ball. It was bouncing off our heads, toes. Everything that could go wrong went wrong for us.”

Patterson Mill (20-6) committed 28 turnovers and shot five air balls, but Calvert (25-1) shot just 25 percent in the first half and still led by only three in the final seconds of the third quarter.

Loube made a three-pointer at the third-quarter buzzer to extend the Cavaliers’ lead to six, and they finally mustered some offensive efficiency as they pulled away in the fourth.

“We know that we have to turn things up for the next game,” senior forward Tiara Lester said. “We need to have less turnovers and capitalize on our offense.”

Junior guard Alexis Smith finished with 13 points and Loube added 10 to lead Calvert, which hadn’t been held to fewer than 45 points in a game since January 2010.

Junior forward Morgan Golec scored 14 points to lead a young Patterson Mill squad that started one senior and two freshman, and was making its first state semifinal appearance in the Bel Air school’s fifth year of existence.

“We’re perfectionists, but it’s better to win ugly than to lose,” Moore said. “We’re just darn happy that we’re playing [Saturday]. We’ve got a chance to go back to back and there’s not a heck of a lot of people who get that chance.”
