It was the Vikings third state crown and first as a member of the 3A.
South Tahoe enjoyed a 1-0 lead at halftime thanks to an Evan Sanchez goal on a breakaway 25 minutes into the fourth meeting between the two league rivals.
The Vikings gave themselves a little bit of a cushion early in the second half on a goal by Kyle Wallace.
However, Sparks answered right back. In the 53rd minute, Kevin Partida sent a corner kick into the box and Edgar Casillas was there to knock it home, cutting the deficit to 2-1.
But that was as good as it got for the Railroaders.
South Tahoe put the game away when Ryan Caro buried a shot with about 15 minutes remaining in the game.
“They just were on the up side today. It wasn’t because of a lack of effort by our boys,” Sparks boys soccer coach Frank Avilla said. “We outshot them and outplayed them for about 30 minutes in the first half. In the second half, it was a pretty evenly matched game. We had our opportunities but just didn’t convert on them.”
