Lyle pulled within one game of Klickitat in Greater Columbia B League Klickitat Division standings last week with victories over Trout Lake and Bickleton.
The Cougars mauled the Mustangs, 60-31, on Feb. 3, then doubled up on the Pirates, 46-23, last Friday.
Klickitat played just once, defeating Glenwood, 61-12, last Saturday.
Those results set the stage for a division-championship showdown between the Vandals and the Cougars on Tuesday in Klickitat.

The Cougars' five seniors totaled 39 points in the final home of their careers in directing Lyle to the victory.

Kristin Brown added nine points and three assists, Christina Grace tallied in eight rebounds, six points and three steals and Melissa Stephens chipped in three boards and three points.

The Cougars got a big jump on the Pirates in the first quarter, streaking to a 16-0 lead. The score was 22-8 at halftime and 32-18 after three periods.
A key to the outcome was Lyle's team defense, which held Bickleton's leading scorer, 6-foot junior Annie Hess, scoreless in the first half and to nine points overall.
