The shortstop is out of the starting lineup for the series finale after getting hit in the left hand by a pitch on Wednesday night. X-rays of the hand were negative.
Since the start of 2013, the Dodgers are 60-32 when Ramirez starts and 41-44 when he doesn't.
Justin Turner, who filled in the final two innings last night for Ramirez, gets the start at shortstop. He has started 21 games at shortstop in his career entering this season, all in 2012-2013 with the Mets.
Facing the left-handed Madison Bumgarner, the Dodgers will start an outfield of right-handed batters with Scott Van Slyke in left field, Matt Kemp in center field and Yasiel Puig in right. Don Mattingly has done this in all three games against southpaws since Kemp returned from the disabled list, including twice against Bumgarner.
The Dodgers have faced a left-handed starter in only four of 16 games this season - once was against Wade Miley in Sydney on Opening Day - and Van Slyke has started all four games.
This is Dee Gordon's first start this year against a lefty. Turner had started the other three games at second base, but with him at shortstop on Thursday plans have changed.
After Gordon and Turner at the top of the lineup, Puig bats third for the first time in his major league career.
Hyun-jin Ryu starts on the mound for the Dodgers, looking to preserve his spotless road record so far. In three starts away from home in 2014, Ryu is 2-0 with 20 strikeouts in 19 scoreless innings, with five walks and seven hits allowed, all singles.
Dating back to 2013, Ryu has pitched 21 consecutive scoreless innings on the road and has allowed one run in his last 33 road innings. In his last seven road starts has a 1.11 ERA with 42 strikeouts and nine walks in 48⅓ innings.
Bumgarner beat the Dodgers on April 5 at Dodger Stadium and is 9-3 with a 2.60 ERA in 13 career games, including 12 starts against them in his career. He has allowed two or fewer earned runs in each of his last six starts against the Dodgers, dating back to 2012.
Bumgarner, who like Ryu throws left-handed but bats right-handed, is 2-for-3 with a grand slam and a sacrifice fly (that nearly went out for another home run) so far this season.
By losing the first two games of this series, the Dodgers have now lost nine of their last 12 series at AT&T Park, dating back to 2010, with a 12-23 record in San Francisco during that span.
