DES MOINES -- Katie Naber tossed a one-hitter and Hannah Petersen a three-hitter to lead No. 6 Jefferson to a pair of victories Saturday at the Jack North Classic.

Naber tossed her gem against English Valleys in a 10-0 win. Jefferson had nine hits. Rachel Sedlacek was 3-for-4.

Petersen spun her gem in a 2-1 win over Iowa City Regina. Sedlacek led off the first inning with a home run, her fifth of the season, and Kenna Fry later added an RBI single for the game winner.

Jefferson (16-3) has doubleheaders Monday through Thursday the coming week. The J-Hawks host No. 7 Iowa City West on Monday, Cedar Rapids Washington on Tuesday, and then travel to Cedar Falls on Wednesday and Kennedy on Thursday.
