EDMONTON, Alberta (AP) — Mark Stone scored the go-ahead goal on a deflection with under 7 minutes left, and the Vegas Golden Knights took a big step toward clinching the top seed in the Western Conference by beating the St. Louis Blues 6-4 in round-robin play. Vegas would be the West’s No. 1 seed with a win against Colorado on Saturday. Despite leading the conference when the NHL season was shut down in March, defending Stanley Cup champion St. Louis can finish no higher than third and needs to beat Dallas on Sunday to avoid the No. 4 seed.
