Las Vegas Lights FC scored four goals in the second half, rolling to a 5-2 win over Phoenix Rising FC on Wednesday night in Las Vegas.
Collin Fernandez and Devin Vega scored for the Rising, who will play at home against Portland Timbers FC 2 on Saturday in the regular-season finale.
The Rising are then hosting a first-round USL playoff game on Friday, Oct. 19.
In its last road match of the season, Phoenix Rising FC will play Las Vegas Lights FC on Wednesday.
A Rising win would clinch one of the two highest seeds in the USL Western Conference Playoffs. Beating Las Vegas would also pull the Rising even with Orange County SC for first place in the conference.
