By PATRICK STEVENS WASHINGTON (AP) — Luis García Jr. homered, DJ Herz allowed just one run in five innings and the Washington Nationals defeated the Miami Marlins 4-1 on Friday night. Jacob Young added an RBI single as the Nationals scored three unearned runs on three Miami errors. Otto Lopez homered for Miami, which has dropped four of five. Washington mustered only one hit in six innings against Marlins starter Edward Cabrera — Dylan Crews’ infield single to lead off the first — but quickly took advantage once he left the game. García ripped reliever Anthony Veneziano’s second pitch into the seats in right field to lead off the seventh inning for his 16th home run of the season to make it 3-1. Two batters later, Drew Millas reached on shortstop Xavier Edwards’ fielding error and stole second when he took off on Veneziano’s pickoff attempt and first baseman Jake Burger made an errant throw.
