Shelby Hogan had six saves and the Portland Thorns held off the determined Utah Royals for a scoreless draw in Sandy, Utah.
Sophia Smith appeared to score in the 21st minute for the Thorns (7-5-3) but she was ruled offside, which was confirmed by a video review. Smith, who was named to the U.S. team for the Olympics earlier this week, is tied for second in the league with 10 goals.
The Royals (2-11-1), coming off a 6-0 loss to the Orlando Pride and sitting in last place, outshot Portland 25-16.
