ST. LOUIS (AP) -- Chicago first baseman Anthony Rizzo says his club has a new, positive attitude this season, and
it begins with first-year manager Rick Renteria.
"He's very upbeat, very positive," Rizzo said. "We've been staying in games and we know we're good and capable of winning them."
Rizzo hit a two-run homer in the first inning of the Cubs' 6-4 loss at St. Louis on Sunday.
Chicago has dropped eight of its first 12 games, but Rizzo says the team is more aggressive than last season, when it got off to a 5-13 start and never recovered.
"A lot of it is guys improving," Rizzo said. "And we've got some new faces. You've got to keep grinding in close games and eventually we're going to flip it around and win some close ones.
"I'm still very positive," Rizzo said.
Chicago rallied from a three-run deficit and put the tying runs on base against St. Louis closer Trevor Rosenthal.
"Every day we're in it until the end," Renteria said. "If we keep pushing, at some point, it's got to turn. I think if we were playing really bad baseball, I'd be concerned. But the reality is, we're showing a lot of fight and we're picking each other up."
St. Louis right-hander Michael Wacha overcame a 46-minute rain delay and Matt Carpenter drove in three runs, leading the St. Louis Cardinals to victory in the rubber game of the series.
St. Louis has won four of six.
Rain has figured in all three of Wacha's starts this season. He actually seemed to embrace a third-inning downpour that halted play against the Cubs.
"I'm used to it," he said. "You just have to accept it and you've got to stay focused. I tried to stay loose and just keep my mind in what I needed to do."
Wacha (2-0) allowed three runs and five hits in 6 1-3 innings Sunday. He gave up a two-run homer to Rizzo on the 16th pitch of the game, but yielded just one run on three hits the rest of the way. He struck out eight and walked one.
"At the start, I was a little erratic, but I was able to settle down a little bit," he said. "I got some quick innings and some quick outs."
Carpenter hit a two-run single in the second inning and added a sacrifice fly in the fourth that put St. Louis ahead to stay at 4-3. He is tied with Yadier Molina for the team lead with nine RBI.
"It felt good to get the job done," Carpenter said. "When you get up in those situations, you just try and put a good at-bat up there and I thought I did that."
Rosenthal gave up a run in the ninth, but retired Luis Valbuena and Emilio Bonifacio with the tying runs on base to pick up his fourth save in as many opportunities.
Chicago starter Edwin Jackson (0-1) allowed four runs and eight hits in six innings. He struck out five and walked three in a grueling 114-pitch effort.
"I didn't feel too bad," Jackson said. "I threw a lot of pitches. I was behind in a lot of counts. They were aggressive, that's a good hitting team."
Jackson also likes the makeup of the team.
"We definitely have a lot of fight in us," he said. "We might come up short sometimes, but we'll give 110 percent as a team."
Jhonny Peralta highlighted a two-run eighth with an RBI double that put St. Louis up 6-3.
After Carpenter singled in two runs in the second, he stole second and scored on Kolten Wong's single for a 3-2 lead.
The Cubs tied it in the fourth on a run-scoring single by Welington Castillo.
Carpenter then gave St. Louis the lead for good with a sacrifice fly to left that brought in Peter Bourjos, who began the fourth inning with a triple.
"We did the things we had to at the right times to win," Carpenter said.
Trailing 4-3, Mike Olt led off the seventh with a double off Wacha. Castillo struck out and reliever Kevin Siegrist retired Darwin Barney and Bonifacio to end the threat.
Siegrist retired all five batters he faced.
"We had some chances, just couldn't get hits at the right time," Rizzo said.
