Howard has hit three homers off Looper in four career at-bats.
"The first one (Thursday), I'll accept that one," Looper said. "The second one was kind of a popup."
Manager Tony La Russa said, "(Looper) made some good pitches and some that were not. He was kind of OK."
The Cardinals hit into three double plays and had just one hit in seven at-bats with a runner in scoring position.
La Russa was less then enthralled with the offense's approach against Moyer. "I thought we took an awful lot of strikes," the manager said. "I don't think we did a very good job of being aggressive with hittable pitches."
PHILLIES 4, CARDINALS 1: The Cardinals lost their second straight series as some of their key hitters continued to struggle. All-Star Ryan Ludwick had just one hit, a homer, in the three games, and both Rick Ankiel and Troy Glaus were 2-for-11.
NOTES AND QUOTES
--LHP Mark Mulder, one day after having to leave a game in which he threw just 16 pitches, was placed on the 15-day disabled list with a shoulder strain. He will have an MRI in St. Louis.
--LHP Jaime Garcia was summoned from Class AAA Memphis to replace LHP Mark Mulder on the roster. For the moment, Garcia will be in the bullpen, but if he stays in the majors, he may get a chance to start after the All-Star break. Garcia has a 3.73 ERA in 18 starts at Class AA and Class AAA.
--CF Rick Ankiel (19), 1B Albert Pujols (18) and OF Ryan Ludwick (18) have a chance to be the first trio of Cardinals hitters to have 20 home runs before the All-Star break.
--1B Albert Pujols, after going 0-for-7 in his career against 45-year-old Phillies LHP Jamie Moyer, had two singles.
--The Cardinals have scored only 13 runs in their last seven games. They have won just one of their last five series.
