The SHS club is now 18-0 on the fall season, including 10-0 in Northern Division I-A league play.
"We played a lot of possession ball today," Sparks coach Frank Avilla said. "We worked on some things we've been struggling with. We played good soccer and had very good touch. We kicked a lot of through balls to space and our set plays worked well. We scored on two of them."
Sparks wasted no time in getting on the scoreboard. It took the Railroaders just seven minutes to find the net. Ruben Pacheco handled those seventh minute scoring chores on an assist from Hector Hernandez.
Hernandez got in on the scoring action himself when he gave Sparks a 2-0 lead with a goal in the 34th minute. Kevin Partida contributed an assist on that sequence.
Sparks had a 3-0 edge at the half. That's because Vicente Cervantes scored for the Railroaders with a minute left before the break, following an assist by Hernandez.
Sparks capped its scoring effort just four minutes into the second half. The Railroaders' final goal of the match came at the 44-minute mark. Partida recorded the goal on an assist off a corner kick from Hernandez.
Sparks got off 14 shots compared to South Tahoe's six. Railroaders goalkeeper Renaldo Hernandez needed just three saves on the day to secure a shutout.
"We played a lot of new people because of some injuries," Avilla said. "Our young kids stepped up and our senior leadership showed.
"But there's always room for improvement. Although our communication is pretty good, it can get better. Our quick touch can get better. Sometimes we're dribbling the ball too much. We'll continue to strive for excellence."
Sparks plays again Tuesday when it hosts Incline at 4 p.m.
South Tahoe showed no mercy in the girls' match. The host Vikings built a five-goal lead by halftime and wound up snaring an 8-0 win over visiting Sparks.
South Tahoe (10-1 league) fired 44 shots on the Sparks goal. Conversely, Sparks managed only one shot against a stingy South Tahoe defense.
"South Tahoe and Elko are the two best teams we've played," Sparks coach Jerry Miller said. "They played for state last year and probably will play for state again this year.
"South Tahoe can possess the ball and then they have pin-point passing. They can connect five passes in a row. Plus, they're awfully strong in their outside game pushing forward and crossing the ball. You have to be very fast to play that way and they are."
Sparks (2-6-3, 2-5-1) meets Incline Tuesday at 2 p.m.
