Kwang Hyun Kim won for the first time in 11 starts, pitching five solid innings and helping himself with a two-run double as the St. Louis Cardinals beat the Arizona Diamondbacks 7-4 Wednesday for a three-game sweep.

Kim (2-5) had lost five straight decisions since his last win on April 23. He stranded six runners through his first four innings, giving up just an RBI single to Asdrubal Cabrera.

Kim retired his last five batters. He struck out five, walked three and allowed three hits as the Cardinals won for the fourth time in their last five games.

Alex Reyes earned his 20th save in as many opportunities. Arizona lost its fourth in a row.

Kim's opposite-field double to left in the second scored Yadier Molina and Edmundo Sosa to give the Cardinals a 2-0 lead. The two RBIs were Kim's first in the majors, and it was also the first extra-base hit for the 32-year-old lefty - he was 1 for 15 in the big leagues before that.

Paul Goldschmidt and Tyler O'Neill each doubled twice and singled, and Molina had a pair of hits. All three players drove in a run.

The Diamondbacks scored three in the eighth on just one hit. Two runs scored on a walk and a wild pitch by Ryan Helsley after he inherited a bases-loaded, one-out situation from Roel Ramirez, who was making his season debut. It is the 20th bases loaded walk allowed by Cardinals pitching this season.

Riley Smith (1-4) gave up four runs over three innings in his first start since May 14. The Diamondbacks were swept for the 13th time this season.

Arizona lost its fourth straight on the road since winning Saturday at San Diego to end a record 24-game road losing streak. The Diamondbacks are a major league-worst 22-60, including 10-36 away from home.

Adam Wainwright (6-5, 3.59 ERA) gets the start of a four-game series at the Colorado Rockies and RHP Antonio Senzatela on Thursday night. Wainwright has five straight quality starts and went 4-1 in June.
