The Okotoks Marauders are a step closer to advancing in the Rocky Mountain Lacrosse League playoffs.

They beat the Calgary Mountaineers 10-5 Thursday night to take a one-game-to-none lead in their best-of-three South Semi-final.

Riley Zeer lead the way with a pair of goals while the rest of the scoring was spread out among eight other players.

Game two goes in Calgary Sunday, according to the RMLL schedule, and if game three is needed it'll be played Monday night at the Okotoks Rec Centre.

The winner plays the Calgary Shamrocks in the South finals.
