An MRI on Carpenter on Monday in St. Louis showed moderate arthritis and a mild impingement in the right elbow. Carpenter, who was placed on the disabled list backdated to April 2, will rest and then be re-evaluated in 10 to 14 days.
This will be the second missed start for Carpenter since he pitched the season opener on April 1.
Meanwhile, the Cardinals' starting pitching without Carpenter continues to be brilliant. A day after Kip Wells held Houston to one hit and no runs over seven innings, Braden Looper, making just his second big-league start, limited the Pittsburgh Pirates to two hits and no runs over seven innings.
Looper reached a career high of 94 pitches when he was pulled.
"I'd be lying if I said it was just normal," said the converted reliever who had made 572 straight relief appearances before starting.
CARDINALS 3, PIRATES 0: Albert Pujols, who had four home runs in six career at-bats against Pittsburgh RHP Ian Snell, singled and doubled off Snell in three at-bats. Pujols, after a double, scored the game's first run on a fourth-inning single by 3B Scott Rolen, who has had five RBIs in the last two games. PH Preston Wilson doubled home the other two runs in the eighth.
NOTES AND QUOTES
--CF Jim Edmonds, still not at top form after two offseason surgeries and a short spring training, was pinch-hit for for the third time this season. It paid off as Preston Wilson doubled home two runs in the eighth inning. "It's early," said manager Tony La Russa. "Jim's just getting his swing back. This was not the time to run him out there against a pitcher like (Damaso) Marte.
--Cardinals starters have given up just three hits and no runs over the last 14 innings.
--RHP Ryan Franklin, who has seized the eighth-inning role, has retired the first hitter he's faced in all four appearances.
--RHP Jason Isringhausen, after being scored on in his first save opportunity Friday, worked a perfect ninth Monday for career save No. 251.
--1B Albert Pujols is a career .400 hitter at PNC Park. "I don't know if there's any park he doesn't hit in," said manager Tony La Russa.
