So far, it has been a good week for the Rost family.

Levis Rost, of the first place men’s Western Michigan squad, won the MAC West Player of the Week award Monday. On Tuesday, his twin sister Casey, who plays on the women’s basketball team, set a Convocation Center scoring record with 32 points to beat NIU 79-69.

Casey, who leads the MAC in scoring at 19.9 points a game, has scored more than 30 points three times this season. Two of her 30-point games have come against the Huskies.

“You give her a little bit of an open look and she’s nailing it,” NIU coach Carol Hammerle said. “Her shot is the same all the time. That’s why she’s so consistent.”

The 5-foot-9 junior scored the first five points of the game and had 13 points midway through the first half.

NIU enjoyed one lead in the game, but 14 seconds later, Casey hit a three-pointer from the left wing to put the Broncos ahead for good.

“Someone on our team hit a three to put us back up,” WMU coach Ron Stewart joked with Rost at the press conference. “I’m not too sure who that was.”

Casey also added four steals, four rebounds and two assists. She had six three-pointers and was a perfect 10-of-10 from the free-throw line.

With NIU down six points with 23.6 seconds to go, it needed to foul to stay in the game. WMU wanted to get the ball to its most reliable free-throw shooter. Stewart repeatedly yelled out “Casey” to let his team know who he wanted to be at the line.

Casey hit four free throws for the Broncos in the last minute of the game to secure the win.

She is second in the MAC at 84.6 percent from the foul line. Last season, as a sophomore, she set the Broncos’ record for free-throw percentage in a season at 90.3 percent.

The win also helped keep the Broncos in a tie atop the entire MAC.

“I felt I had to do whatever I could to help the team win,” Casey said. “I was looking for the post players tonight, but if the open shot was there, I was going to take it.”
