He has hit four home runs in four games after the drought.Pujols dismissed the idea that his recent struggles were related to injuries.Pujols had a season-high four RBI and took over sole possession of second place on the Cardinals’ RBI list with 1,150. Pujols trails only Stan Musial, who had 1,951 RBI for St. Louis.The Cardinals, who will begin a three-game series against the NL Central-leading Reds on Monday, won their first series at Wrigley Field since taking two of three from the Cubs on April 20-22, 2007.Wainwright (7-3) improved to 5-0 in his past eight starts against the Cubs.

It was Pujols third multihomer game of the season and 36th overall and he is only one game behind Musial for most in club history.Pujols’ third home run of the game came off John Grabow in the ninth. He hit a 1-2 pitch to straightaway center for his 12th of the season. After Holliday singled, Freese hit his fourth home run of the season.Geovany Soto hit a home run in the seventh for the Cubs, who wound up splitting a six-game homestand.In the second inning with two outs, Aramis Ramirez tried to score from second on Starlin Castro’s single, but center fielder Jon Jay threw out Ramirez at the plate.The Cubs saw another scoring chance spoiled in the fourth. With the bases loaded and one out, Castro hit a sharp grounder to shortstop Brendan Ryan to set up an easy inning-ending double play.
