In a tune up for the playoffs, the Kelowna Raiders will host the Kamloops Rattlers Friday  in Thompson Okanagan Senior Lacrosse League action.

Face off at Memorial Arena is 8 p.m.

The Raiders and Rattlers will meet again in the best-of-three opening round of the postseason next week.

The Armstrong Shamrocks, who will finish first in TOSLL, have the first round bye.

Kelowna slipped to 3-6 on the season with a 7-4 loss to the 'Rocks Friday night in Vernon.

Despite numerous power play opportunities, the Raiders were unable to solve Armstrong goalie Chad Pieper .

Missed passes and lack of ball possession allowed the Shamrocks to take full advantage of the Raiders' mistakes.

Led by goalie Graham Cousins, the Raiders defence managed to contain the Shamrock shooters for much of the second half of the game. Ryan Lindstrom, Nick Evans, Joe Brown and Matt Gorges scored for the Raiders who were coming off a three-week break.

Joel Castle had a hat trick for Armstrong.
