For the last two seasons, the Rockies have struggled mightily against the Giants.
In 2021, the Giants were 107-55 and actually beat out the Dodgers for the NL West crown. Last season, the Rockies went 4-15 against San Francisco. This year, the Giants are 71-77, which is seven games ahead of the Rockies, but 32 games back in the NL West and 9.5 back in the NL Wild Card race. Even with the Giants slide, they are still way ahead in the season series, winning nine of 14 contests so far.
In other words, the Rockies are 9-24 in their last 33 games against San Fransisco, including losing the first two in the current four-game series.
