Beltran's 2 HRs, 6 RBIs Lead St. Louis to 6-1 Win Carlos Beltran has been around long enough to know that there are good times and bad times in a long season. Things are very good for the St. Louis slugger right now. Beltran homered in his first two at-bats, including a grand slam, for six RBIs, and the Cardinals beat Arizona 6-1 on Tuesday night, handing the Diamondbacks their fourth loss in a row. 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. "His swing and his approach is so simple," St. Louis manager Mike Matheny said. He's got a good idea of what he's looking for and doesn't try to do too much when he gets it. That's just smart hitting from a guy that's been around for a while. 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.

Kennedy (3-2) threw five scoreless innings after Beltran's slam but the Diamondbacks lost for the sixth time in seven games. They have dropped nine of their past 11 at home. "We have to get our confidence back," the Diamondbacks' Justin Upton said. We have had a couple of tough loses. We have gotten beat up but good teams come out of these things and pick themselves up. I think we have the group to do it. 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," 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.
