ST. LOUIS (AP) — St. Louis infielder Matt Carpenter finally got the best of close friend Jake Arrieta.

But he isn’t going to brag about it.

Carpenter slammed a two-run homer, Yadier Molina homered twice and Adam Wainwright threw seven shutout innings to lead the Cardinals to a 5-0 win over the Chicago Cubs on Sunday.

Carpenter entered his third-inning at-bat with a 1-for-31 career slate against Arrieta. The two were college teammates at TCU. Carpenter served as a groomsman at Arrieta’s wedding.

“It was great to get out there and finally have some success against him,” Carpenter said. “He’s given me a hard time over the years, we jab back and forth, but I won’t rub that kind of stuff in.”

Arrieta (4-3) realized that his success against Carpenter was not going to last forever.

“A hitter like that, regardless of the history — you make a mistake and they’re going to make you pay for it,” Arrieta said.

Carpenter came into the game 0 for 27 against Arrieta in the regular season and 1 for 3 in the postseason. He grounded back to the mound in his first trip to the plate.

“I always kid him that I’m a .300 hitter against him in the postseason,” Carpenter said.

Molina recorded the third multi-homer game of his career. His last came on Aug. 21, 2011 at Wrigley Field. He drilled a two-run homer off Arrieta in the second inning.

Swinging a pink bat in honor of mother’s day, Molina added a solo blast off Brian Duensing in the eighth. Molina pointed to his mother, Gladys, in the stands as he headed into the dugout.

“It’s special, every time you have your family and your mama here,” Molina said. “I got lucky and put a good swing on it.”

Wainwright (3-3) allowed four hits in a 102-pitch stint. He struck out three and walked four. Wainwright had given up four earned run in each of his last three starts.

“It’s a good outing to build off,” Wainwright said. “I can still get better. I can still have better fastball command. It’s certainly a stepping stone.”

Trevor Rosenthal and Kevin Siegrist each pitched a perfect inning to complete the four-hitter.

Chicago had runners on in six of the first seven innings.

“Overall, we’re not doing a good job with runners in scoring position,” Chicago manager Joe Maddon said.
