San Francisco Giants vs. Colorado Rockies preview
The Giants wrap up their home slate Friday night against a Rockies team that's limping to one of the worst finishes in franchise history at 43-115.
Colorado's offensive struggles have been glaring all season, managing just 3.7 runs per game while striking out nearly 1,500 times, making them prime targets for a Giants pitching staff that's been solid with a 3.88 ERA.
German Marquez takes the hill for the visitors carrying career numbers that suggest he can keep things competitive, though his 4.64 ERA this season tells a different story.
The Giants counter with Kai-Wei Teng, who's battled command issues in his brief MLB stint with a 7.39 ERA and concerning 1.716 WHIP through 40 innings.
San Francisco sits at 78-81 and playing out the string, but Oracle Park has been kind to them this year and they'll want to send their home fans off on a high note.
With both teams' seasons effectively over, this becomes about individual performances and setting the table for 2026, though the talent gap between these clubs remains obvious.
