PHOENIX -- Beaten, bloodied and now double digits out of first place.In a microcosm of their 2012 season to date, the D-backs turned in a lackluster performance on Monday by striking out seven times, committing an error, failing to deliver a clutch hit and watching their bullpen collapse while the game was still close. Mustering just six hits while the bullpen squandered any chance for a rally, the D-backs fell to the National League West-leading Dodgers, 6-1, and dropped to 10 1/2 games off the pace a quarter of the way through the season. "In a perfect world, yes," said Willie Bloomquist said when asked if now is the time to start catching the Dodgers. "They are playing good baseball. They've played good all year. We've got to worry about ourselves though. We're capable, we just have to get on a roll." The loss had an extra sting for the D-backs, as All-Star catcher Miguel Montero left the game in the sixth inning with a mild left groin strain. His status moving forward is day to day. "I didn't feel any pop, thank God," Montero said. "It was just kind of crampy. It's still early in the season, you don't want it to get worse. You just take it step by step. Good news is it feels a lot better." Arizona rookie left-hander Patrick Corbin pitched admirably, tossing 5 1/3 innings and allowing only two earned runs on six hits. The D-backs' bullpen allowed four runs in the seventh and eighth innings to leave the final score inflated. "I felt like I came back and worked a lot better and got some bad swings," Corbin said. "I kept the team in the game. I was getting guys out in front a little bit with my changeup." With the defeat, the D-backs dropped to 3-13 in their past 16 home games. Dodgers lefty Chris Capuano continued his torrid pace to start the 2012 campaign with six strong innings, surrendering one run on four hits. "He's very good at what he does," Bloomquist said. "He's good at changing speeds, changing eye level and hitting his locations. When he's hitting he's spots, he can be pretty tough. He never really left anything out over the plate." The Dodgers jumped on Corbin early to the tune of five hits in the first two innings, highlighted by a Matt Treanor two-run homer to left field on a first-pitch fastball in the second. From there, however, Corbin gave up just one hit. "When you least expect it, I was trying to stay in the middle part and I got the barrel out," Treanor said. "I didn't think it would leave the park." Capuano sat the D-backs down in order their first trip through the lineup, but Bloomquist led off the fourth inning with a triple that kicked off the left-center-field wall and back toward right field, opening the door for a potential inside-the-parker. "I saw it kick away," Bloomquist said. "I didn't know how far, crazier things have happened. I had my mind set just in case [third-base coach Matt Williams] sent me." The next batter, Aaron Hill, singled to center to make the score 2-1. After the D-backs stranded a runner in scoring position in the fifth, the Dodgers worked two of their first three batters of the sixth on base with the help of a walk and an error from third baseman Josh Bell, playing in his first game for the D-backs. The hitless rally prompted Kirk Gibson to go to the bullpen and bring in Craig Breslow, who retired the next two Dodgers to get out of the inning unscathed. "He threw the ball well. He made one bad pitch," Montero said of Corbin. "Other than that, he threw outstanding, couldn't get any run support, unfortunately." The Dodgers extended their lead to 3-1 in the seventh when Phoenix native Andre Ethier hit a home run into the pool pavilion off Breslow. Justin Sellers' RBI triple and James Loney's pinch-hit two-run homer in the eighth off Bryan Shaw capped the Dodgers' night. "Things just got out of hand for us," Gibson said.
