LOS ANGELES -- Getting shut out by Clayton Kershaw was the least of the St. Louis Cardinals problems. They may have to do without first baseman Lance Berkman for a while because of an injured right knee. Kershaw outdueled Jake Westbrook with a six-hitter for his fourth career shutout, leading the Los Angeles Dodgers to a 6-0 victory on Saturday night. "The first couple of innings I threw mainly fastballs," said the 24-year-old left-hander, who is 14-1 with a 1.40 ERA in his last 19 starts at home. "Once I established it, I used my breaking ball more, and the combination worked. They have a great lineup, but losing Lance Berkman is a big blow for them." Berkman injured himself stretching for a throw from shortstop Rafael Furcal on Justin Sellers groundout for the third out of the second inning. Matt Carpenter took over at first and committed a fielding error on a hard-hit grounder by former Cardinal Adam Kennedy in the fourth, allowing the games first two runs to score. The switch-hitting Berkman, a six-time All-Star and the NL comeback player of the year in 2011, has played in only 13 games this season and is batting .333 with a homer and four RBIs. In Friday nights series opener, he homered as a pinch-hitter against Dodgers closer Kenley Jansen with two out in the ninth to tie the score, before the Cardinals lost in the bottom half on a bases-loaded walk. The homer ended the longest season-opening home run drought of his career after 40 at-bats. Berkman had just come off the disabled list last Sunday after being sidelined for 21 games because of a strained left calf he aggravated while chasing a popup. Another trip to the DL is a distinct possibility, judging by the way he was limping around in the clubhouse. "I wish I knew," said Berkman, who has been on the DL five times. "Were just going to wait and see what the MRI says, but it just doesnt feel right. It buckled on me twice, and I dont know why it did that. I was able to move around OK in here, and then it buckled again. So I have to be careful with it. Its not too painful, but its just a weird feeling. I wish I could describe it. Theres a little bit of instability thats mildly concerning." Kershaw did not walk a batter for the third time this season while lowering his ERA from 2.22 to 1.90. "Its scary, but he keeps getting better," catcher A.J. Ellis said. "It just gives us a ton of confidence in this clubhouse that when its his day to pitch, hes going to give us an awesome chance to win the game. You know what youre getting with Kersh. Hes the same consistent guy on and off the field, and he knows hes got a job to do no matter what the circumstances. He wants every game real badly, but you could tell he really wanted this one." The reigning NL Cy Young winner earned the seventh complete game of his career on 116 pitches, striking out four and not allowing a runner past second base against an offence that came in leading the NL in team batting average, runs, homers, on-base percentage and slugging percentage. Sellers triggered a four-run seventh inning with his first home run of the season for the NL West-leading Dodgers, who improved the best record in the majors to 27-13. The Dodgers beat the defending World Series champions for the sixth straight time -- their longest winning streak against the Cardinals since an eight-game stretch from July 24, 1975 through May 12, 1976. Westbrook (4-3) was charged with four runs -- three earned -- and six hits in 6 1-3 innings. The 34-year-old right-hander, pitching at Dodger Stadium for the first time in his 12-year career, departed after giving up Kershaws opposite-field double off the glove of left fielder Matt Holliday. It was Kershaws first extra-base hit after hitting 28 singles over five seasons. Tony Gwynn Jr. greeted Eduardo Sanchez with a single that drove in Kershaw. The Dodgers got two more runs that inning when Gwynn scored on Sanchezs wild pitch and Andre Ethier added an RBI single that increased his NL-best RBI total to 36. Westbrook knew he would have his work cut out for himself facing the Dodgers ace, but he didnt let that distract him. "You try not to do that, because you always want to go out there and throw a decent ballgame and put up zeros no matter who youre facing," Westbrook said. "If you put too much added pressure on yourself, its really counter-productive. So you just go out there and pitch your game and do the best you can." Ellis doubled his first two times up, and has reached base with a hit or a walk in 31 of his first 32 games -- including the last 28 in a row. He entered Saturday with a .459 on-base percentage, the second-highest in the majors behind the Mets David Wright (.510). Notes: Dee Gordon, the Dodgers regular SS and leadoff batter, got the night off after going 2 for 31 with 10 strikeouts and one walk in the previous seven games. Mattingly said before the game that he will sit him for a few days. ... Kershaw, who led the NL with 248 strikeouts last season, has made 13 consecutive starts without reaching double digits in strikeouts. ... In eight starts this season, Westbrook has yielded just one run over the first three innings. He has made only two other regular-season appearances against the Dodgers, both in relief for Cleveland in 2003. www.nbaofficial.com . The latest one might be the toughest. The Marlins led 6-1 in the eighth inning before Heath Bell coughed up four runs in the ninth to the St.For some of Canadas top athletes, the Canadian Track and Field Trials are the final step towards qualifying for the London 2012 Olympic Games. Each week, CTVOlympics.ca looks at some of the names to keep an eye on as we count down to the Trials in Calgary from June 27-30. DISCIPLINE: Mens 20km Race WalkNUMBER OF OLYMPIC BERTHS AVAILABLE: Three. *The IAAF allows a maximum of three athletes per country per event if the three athletes have each reached an A standard time. TOP CONTENDERS: Inaki Gomez – Vancouver, BCWHAT THEY NEED:Gomez is the lone walker that has met the A+ standard time in the event. That means hell need just to place top three at Trials to book his Olympic ticket. Since he is currently the only Canadian in position to claim an Olympic berth, it would be considered a major upset if Gomez failed to qualify for London 2012.WHAT YOU SHOULD KNOW:Because of the gruelling nature and distance of the event, the race walk at Trials will only be a 10km race. This means that any athlete who wants to make it to the Olympic Games in Race Walk would need to have reached the Olympic qualifying standard time prior to Calgary.Gomez achieved the A+ standard time (1:21:07) early in the season, finishing eighth at an IAAF event in China with a time of 1:21:05 – his career best time in thee event.dddddddddddd He followed that up with another A standard time (1:22:30) at last months meet in Saransk, RUS. Gomez finished 14th in that race with a time of 1:21:58.There was another Olympic hopeful, Evan Dunfee, looking to join Gomez in London, but it appears that his hopes have faded. While Dunfee achieved better than a B standard time this qualifying period—he completed a personal best 1:23:45 at the Naumburg International in Germany—but because of Gomezs success, Dunfee needed to secure an A standard time ahead of Trials.There is only one IAAF-sanctioned event left before Trials, which runs June 17th in Italy. Dunfee, who is not yet scheduled to participate in that event, would need an A standard to be eligible to qualify for the Olympic Games at Trials.MEDAL HOPES IN LONDON 2012:Gomezs personal best was just a few seconds off the national record set by Arturo Huerta in July of 2000. Realistically, Gomez would need to get his time under 1:20:00 just to break the top 15 in London 2012.Gomez has said in interviews that the goal is not necessarily to win a medal now, but to continue to build experience the Rio 2016 Summer Games.The best time this year is held by Italys Alex Schwazer, who finished a 20km race walk in 1:17:30.
