Mercedes DTM boss Ulrich Fritz admits today has been a 'day to forget' after his C63 Coupe outfit score just the solitary point at the Hockenheimring.
HWA's Paul di Resta salvaged a point for Mercedes with tenth position in race one after moving up slightly from his twelfth place qualifying effort.
Mercedes' prospects for the sprint race had already looked less than favourable after not one C63 Coupe made the top-ten order in qualifying.
As the nearest Mercedes to Audi and BMW, former F1-driver Di Resta finished 19 seconds behind eventual winner Miguel Molina.
Fighting for every point he could muster, Di Resta said he paid the price for an aggressive DRS strategy late in the race.
"That was a hard-fought point. I had no choice but to use the DRS relatively early in the race. Consequently, I was unable to use it later on for overtaking," Di Resta said.
"On the penultimate lap, I got past Farfus but was unable to defend myself against Jamie (Green) who still had DRS in reserve. I hope tomorrow will be better for us."
Mercedes boss Fritz blamed a poor direction in set up as the cause for his team's not so stellar Saturday.
"You can forget today. We just didn't find the right setup to finish in the points, but we tried out one or two things in the race in order to achieve a decent end to the season."
