Corey Seager walked, singled twice, hit his fifth double and his first Major League home run in tonight’s 9-5 Dodger victory, extending his streak of consecutive plate appearances on base to nine — a Los Angeles Dodger rookie record.

According to the Elias Sports Bureau, Seager has surpassed Pedro Guerrero (1980) and Jerry Sands (2011), who each reached base in eight consecutive trips as rookies.

Seager’s homer in the fifth was one of four in the game by the Dodgers, who burst out to a 7-0 lead by the third inning and maintained their 7 1/2-game lead over the Giants in the National League West. The 21-year-old, who drove in runs in his first three at-bats tonight, has an astonishing .568 on-base percentage and .733 slugging percentage in his first 37 MLB plate appearances.

Joc Pederson went 3 for 5 with his 25th homer of the season, tying him with Del Bissonette (1928) and Joe Ferguson (1973) for second in Dodger history for homers by a rookie behind Mike Piazza, who had 33 in 1993. (I’m not convinced Ferguson was a rookie in 1973, but according to Baseball-Reference.com he was.)

It wasn’t a free night of bliss for the Dodgers, who saw Carl Crawford become the latest to leave a game with hamstring issues. He is listed as day to day. Crawford hit a leadoff homer for the Dodgers — their third in their last four games, and fourth straight game with a homer from their leadoff batter.
