The Cardinals' 12-2 loss was their third straight defeat by six runs or more. They have scored three or fewer runs in 18 of 25 games this year and have earned their last-place station in the National League Central, regardless of the aftereffects of the death of reliever Josh Hancock early Sunday.
"How different is this from the way we've been playing?" said manager Tony La Russa, refusing to blame the team's grief. "Not nearly good enough. And we're all involved.
"We're not making it a very good competition. Including the guy you're talking to (himself)."
Looper, who had considerable difficulty handling left-handed batters last year, had held them to a .184 mark before Tuesday. But, while he retired Prince Fielder twice, Geoff Jenkins had three of his four hits against Looper.
The Cardinals surrendered 16 hits to Milwaukee and even lost to Ben Sheets. They had been 14-4 against Sheets for his career.
"I believe in this club ... but we've got to acknowledge we've got problems," La Russa said.
BREWERS 12, CARDINALS 2: Braden Looper was roughed up for 11 hits in five-plus innings, and Milwaukee rolled to a win at Miller Park. After falling behind 2-0, the Brewers poured it on against Looper, Randy Flores, Brad Thompson and Dennis Dove.

--LF Chris Duncan cracked his fifth homer of the season for one of the two Cardinals runs. RHP Braden Looper, the losing pitcher, drove in the other with his second hit of the season.
--SS David Eckstein, hitting just .226 with an on-base percentage under .300, was dropped from the leadoff spot for the first time in his three seasons with the team and batted eighth.
