SAN DIEGO — Manny Machado hit two home runs and drove in three runs for the San Diego Padres, who beat the St. Louis Cardinals 4-2 on Friday to extend their winning streak to eight, their best streak of the season.

He was driving in compatriot Juan Soto, who reached base with a double.

In the sixth inning, Machado opened the game with a home run off Dakota Hudson, giving the Padres a 2-1 lead.

Venezuelan Robert Suarez (4-2) won.

And the Venezuelan Cardinals, Jose Herrera, 3-0. Dominican Jose Firmin 3-0.
