Gonzalez has six home runs and 14 RBI in 13 games against the Padres this season, hitting .353/.377/.784 against his old team.
Since getting traded from San Diego after the 2010 season, Gonzalez is hitting .321/.347/.556 with 14 home runs, 13 doubles and 47 RBI in 60 games against the Padres, the third-highest active batting average against the Friars (Carl Crawford is first, at .346).
The bulk of that damage this season for Gonzalez came in the first three games of the season, when Gonzalez set a major league record with five home runs to start the year. But with six games remaining against San Diego this year, Gonzalez is two home runs shy of the record for most home runs by a Dodger against the Padres in one season, set by Jimmy Wynn in 1974 and matched by Darryl Strawberry in 1991.
Gonzalez went 0-for-5 in Thursday's series opener, and is hitting .281/.351/.498 on the year. But with that 0-fer on Thursday Gonzalez saw his slugging percentage drop below .500 after a game for the first time all season. His last season with a .500 slugging percentage was in 2011 with the Red Sox, when he hit .338/.410/.548 in his first year in Boston.
Gonzalez is 10-for-32 with two home runs and four walks against James Shields, hitting .313/.378/.500 against Friday's Padres starter. One of the home runs came this season, on Opening Day.
On the other side, Justin Upton was 3-for-3 with a pair of doubles and a walk, driving in one run and scoring two in Thursday's 10-7 Padres win.
Upton this season is hitting .306/.358/.714 with five home runs and 18 RBI in 13 games against the Dodgers. Since the Dodgers moved to Los Angeles in 1958, only 24 players have had more RBI in a season against the Dodgers than Upton this year, and he still has six more games to do some damage.
The only Padres with more RBI in one season against the Dodgers are Chase Headley (20 RBI in 18 games in 2012) and Dave Winfield (19 RBI in 18 games in 1979).
The top RBI men against the LA Dodgers in a season is a collection of greatness — Willie Mays (32 RBI in 22 games in 1958), Frank Robinson (26 RBI in 21 games in 1961), Ernie Banks (25 RBI in 22 games in 1959) and Todd Helton (23 RBI in 19 games in 2001).
Upton is 2-for-7 with a walk and three RBI against Mike Bolsinger, starting for the Dodgers on Friday night.
