Carpenter is having a Cy Young-type season at 14-4 with a 2.26 ERA after 20 starts. The 30-year-old right-hander hopes to join Chicago White Sox righty Jon Garland (15-4) as the majors only other 15-game winner.
In his last seven starts, Carpenter is 6-0 and has allowed just three runs in 59 2-3 innings for an 0.50 ERA.
Jake Peavy and Trevor Hoffman combined on a three-hitter and Robert Fick singled in the game-winning run with one out in the bottom of the ninth as San Diego snapped a season-high eight-game losing streak with a 2-1 victory over the Cardinals on Wednesday.
The Padres climbed one game above .500 (51-50) and maintained a three-game lead over second-place Arizona in the mediocre NL West.
San Diego got some bad news Wednesday when catcher Ramon Hernandez decided to have surgery on his injured left wrist.
Hernandez sought a second opinion from a specialist in Los Angeles, who confirmed that he has a small cartilage tear. Surgery is scheduled for Friday and Hernandez is expected to be out for three to six weeks.
“It’s a blow to the ballclub to lose your catcher,” San Diego manager Bruce Bochy said. “He’s done such a great job. But you’ve got to move forward. We’ve been through a lot this year. A lot of clubs have. That’s all we can do at this point.”
The Padres will continue to have Fick and Phil Nevin catch until they can acquire another starter. Fick filled in admirably when Hernandez was on the disabled list from June 18-July 7, and Nevin caught Tuesday night.
