CINCINNATI (AP) -- The season has brought one setback after another for the St. Louis Cardinals -- manager Tony La Russa's drunken-driving arrest, reliever Josh Hancock's death, a series of injuries to everyday players.
The defending World Series champions may be running out of resilience.
The Cardinals lost all seven games on their trip, capped by their first three-game sweep in Cincinnati since July 1998. It's their first winless trip of at least seven games since May 1972, when they went 0-7 in Cincinnati and Pittsburgh.
It's a bad time to be making historical references.
"We're a little flat, things aren't going our way and we're not playing good baseball," outfielder Jim Edmonds said. "All those add up to losses. It's really no different than it was at the beginning of the year. It's just a bad time for it right now."
The Cardinals had surged from 10½ games out at the end of June to within a game of first place in the NL Central before hitting the road and hitting the skids. They are five games behind first-place Chicago, which beat Houston 6-2 on Thursday night, and 4½ games behind Milwaukee, which was idle Thursday.
"It's just been -- I don't even know how to word it," said Kip Wells (6-17), who lost his fourth straight start. "It's just been tough. We haven't caught any breaks."
Votto doubled home a pair of runs in the fifth off Wells, and Ross followed with his first homer since July 23. The catcher had been 1-for-15 since returning from a concussion on Aug. 28.
Aaron Harang (15-4) gave up three hits and three sacrifice flies -- two by Albert Pujols -- in seven innings. David Weathers gave up Edmonds' RBI single in the ninth before becoming the ninth Cincinnati closer to reach the 30-save mark.
The sweep was particularly pleasing for the Reds, who were swept in a three-game series in St. Louis from Aug. 31-Sept. 2.
"We went into their place and they smacked us around, so it was nice to come back and take three from them, especially with the playoffs right around the corner," Harang said. "It'll make them work that much harder to get back in the race."
The Reds were still holding out hope of getting back into contention until they landed in St. Louis two weeks ago. Since then, they've been relegated to playing it out.
"We went in there kind of on a roll and they stuck it to us," Ross said. "I don't know if we knocked them out of playoff hunt, but we did a good job of hurting their chances."
It was the Cardinals' costliest trip of the season by far.
In addition to losing precious games in the standings, they lost third baseman Scott Rolen, who had shoulder surgery on Tuesday, and outfielder Chris Duncan, who aggravated a hernia and is likely out for the season.
Now, they're running out of time. They play four games against the Cubs this weekend in St. Louis and have three left in Milwaukee -- the two teams they're chasing.
The Cardinals faced the Reds' top two starters during the series and didn't do much against either. They lost to Bronson Arroyo 7-2 on Wednesday night.
David Eckstein led off Thursday's game with a double and scored on a sacrifice and Pujols' sacrifice fly. Eckstein was the only Cardinal to manage a hit off Harang in the first five innings.
The Reds wasted several chances against the enigmatic Wells, who lost seven straight games earlier this season and has now lost his last four starts. The Reds left the bases loaded in the third, when Edwin Encarnacion popped out.
They loaded the bases again in the fourth but managed only Jeff Keppinger's sacrifice fly that tied it at 1. Votto's RBI double -- his third hit of the game -- broke the tie in the fifth, and Ross followed with his first homer in 53 at-bats.
Another sign of how things are going for St. Louis: It was only the third homer off Wells in the right-hander's last 71 innings.
Wells has given up 21 runs in 18 innings during his four-start losing streak. ... Slumping outfielder Rick Ankiel was out of the Cardinals' lineup. He pinch-hit, stayed in the game and went 0-for-2, leaving him in a 1-for-23 rut. ... Reds outfielder Josh Hamilton was out of the lineup with a strained right hamstring. Shortstop Alex Gonzalez was out with a sore left knee. ... Weathers is 30-for-35 in save chances. He's the first Reds reliever to get 30 saves since Danny Graves in 2002. ... The Reds head to Milwaukee, where the Brewers will face starters Tom Shearn, Kirk Saarloos and Matt Belisle in a three-game series.
