Arizona has dropped nine of its past 11 at home, not exactly the situation the defending NL West champions expected.Justin Upton, whose ninth-inning single was just his fourth hit in his past 25 at-bats, says the Diamondbacks "have to get our confidence back.""I know the character of this ball club and we are going to be fine," he said. "We just have to find it, find it and pick ourselves up and get a little streak going."Carlos Beltran homered in his first two at-bats, including a grand slam, to provide all six St. Louis RBIs.Beltran, who had one of the Cardinals' five homers in their 9-6 series-opening win on Monday, hit a two-run homer off Ian Kennedy in the first, then cleared the bases with a shot into the swimming pool area in right-center in the seconds, his 10th career grand slam.He has 10 home runs this season.Beltran's performance came a week after he went 4 for 5, including two homers, for a career-high seven RBIs against Pittsburgh."It's confidence, it's results, it's a little bit of everything," Beltran said. "It's being able to come to the ballpark and have good BP (batting practice) sessions, staying inside the ball, things like that. You can carry those to the games. I'm just going through good times. In this game, you go through ups and downs."Jake Westbrook (4-2) blanked the Diamondbacks on four hits through seven innings.Kennedy (3-2) threw five scoreless innings after Beltran's slam but the Diamondbacks lost for the sixth time in seven games."Plain and simple St. Louis is playing much better than us," Arizona manager Kirk Gibson said. "They beat us in every aspect of the game. It doesn't mean that it will be that way all year, but right now we are not playing very well. They are playing very well."The Cardinals won their third straight and can complete a three-game sweep in the desert on Wednesday night.St. Louis catcher Yadier Molina left the game in the ninth inning after being hit in the back of his gloved hand trying to snag a pitch by reliever Mitchell Boggs. Preliminary X-rays were negative."That's good news because the ball hit me pretty good," said Molina, who was expecting a slider but got a fastball. "I feel good. We'll see what happens tomorrow."Several seasons ago Molina broke a bone in the same spot.Westbrook struck out eight and walked two. Only one Arizona base runner reached second against the sinker-throwing St. Louis right-hander."You could see the movement on the ball from the side," Cardinals manager Mike Matheny said. "When you see a sinker moving that much you know that they're going to have a hard time over there trying to put good wood on it."Aaron Hill singled three times off Westbrook, two of them infield hits.Jon Jay opened the game with a triple past diving center fielder Gerardo Parra, then Beltran hit Kennedy's 1-0 pitch deep into the right field seats to make it 2-0 in a hurry.The Cardinals, who led 3-0 after one and 7-0 after five on Monday night, took a 6-0 lead in the second as Kennedy struggled with his control. Skip Schumaker doubled with one out, then Westbrook drew a two-out walk. Jay was hit by a pitch to load the bases and bring up Beltran, who lofted a 2-1 pitch into the swimming pool area in right field for the 32nd multi-home run game of his career.Kennedy settled down after that, retiring the last 13 batters he faced, 15 of the last 16. He struck out Beltran twice. But the damage was done.The Arizona ace, who went 21-4 last season, lost consecutive starts for the first time since September 2010. He was beaten 2-1 at Washington last Wednesday, ending his nine-game winning streak. The six runs were the most he has allowed in his past 23 outings.Kennedy struck out six, walked two and hit a batter.The Diamondbacks averted a shutout when Upton led off the ninth with a single and scored on Miguel Montero's double.
