ST. LOUIS -- The last-place St. Louis Rams continue to show opponents that they know how to compete against the league's best.
This time, they finished the job against the NFL's No. 2 offense, which hadn't scored fewer than 21 points and had scored 30 or more five of the previous six.
Shaun Hill was effective in his first start since regaining the quarterback job and the defense made the stops that counted.
"We didn't execute very well and I just think I didn't play very well," Manning said. "No excuses. I have to play better and we have to score more points than seven."
Quinn spun Manning around before Donald took the quarterback down.
"I got the opportunity to clean him up," Donald said. "You've got to take a big quarterback down when you can."
Thomas (ankle) was sidelined in the first with two catches for 3 yards and ruled out in the third, Ball (groin) got limited work before aggravating an injury that kept him out the previous five games. Sanders (concussion) was ruled out after a hit from Rodney McLeod on a deep sideline throw in the third.
Hill was 20 for 29 for 220 yards and a touchdown with no interceptions in his first start since injuring a thigh in the first half of the opener.
The 34-year-old Hill got his job back after Austin Davis made too many mistakes. He guided a turnover-free offense.
"I certainly had the butterflies going," Hill said. "It was a lot of fun to be back out there."
Zuerlein hit three short field goals earlier, then connected from 55 and 53 yards in the fourth quarter. He last kicked five field goals in 2011 for Division II Missouri Western against Missouri Southern.
"Lots of times, you don't get many opportunities," Zuerlein said. "Today, they came in bunches."
