BALTIMORE (AP) — Alcides Escobar doubled in the go-ahead run in the ninth inning, Mike Moustakas extended his home run-binge and the Kansas City Royals remained perfect in the playoffs, beating the Baltimore Orioles 6-4 Saturday for a 2-0 lead in the AL Championship Series.

Lorenzo Cain had four hits, scored twice and drove in a run for the wild-card Royals, who are 6-0 in the playoffs this year, including 4-0 on the road.

Moustakas hit his fourth home run of the playoffs. Overall, Kansas City has won nine straight postseason games, a string dating way back to the 1985 World Series.

The best-of-seven series shifts to Kansas City on Monday for Game 3 with the Royals halfway toward reaching the World Series once again. Former Oriole Jeremy Guthrie will start for the Royals against either Wei-Yin Chen or Miguel Gonzalez.
