PRETORIA, South Africa -- A South African police officer swung a cricket bat at Oscar Pistorius bullet-marked bathroom door during his murder trial on Wednesday, using two key pieces of evidence to re-enact the night he killed his girlfriend. Police Col. J.G. Vermeulen faced tough questioning from Pistorius defence lawyer, who tried to discredit the police investigation of the shooting and alleged that Vermeulen, a forensic expert, made glaring missteps in his analysis. Pistorius lawyers secured bail for him last year after contending that police contaminated or tampered with evidence from the home where he fatally shot Reeva Steenkamp, firing through the bathroom door as she cowered inside during the pre-dawn hours of Valentines Day 2013. Pistorius says the killing was a mistake; the prosecution alleges the 27-year-old double-amputee intentionally shot Steenkamp after an argument. The actual door that Pistorius shot through a year ago was erected in the Pretoria courtroom Wednesday, and the bat he used that night was used in the demonstrations. There was even a toilet cubicle behind the door, recreated to the exact specifications of the small area of Pistorius bathroom where the 29-year-old model was fatally shot, Vermeulen said. Below the doors handle, four bullet holes were clearly visible. Steenkamp was hit three times in the hip, arm and head. One shot missed, the court has heard. Pistorius says he used the bat to break down the door after realizing he shot Steenkamp, mistaking her for an intruder. Kneeling, Vermeulen swung the bat to show how he believed Pistorius struck the door from a low angle, indicating he was on his stumps at the time. Defence lawyer Barry Roux insisted Pistorius was wearing his prosthetic legs, saying the bat marks on the door were low because he swung with a bent back. The back-and-forth over whether Pistorius, the first amputee to run at the Olympics, was on his prosthetic limbs or not is important because it could match parts of his story that he accidentally shot Steenkamp, or expose inconsistencies in it. Last year, prosecutors maintained Pistorius was on his prostheses when he fired through the door, arguing the runner planned the killing while putting on his artificial limbs. But in a reversal, prosecutor Gerrie Nel said in court Wednesday that he did not dispute the defences contention that the runner was on his stumps when he opened fire. The athlete has said he fearfully approached the bathroom on his stumps and shot Steenkamp by mistake, thinking she was an intruder hiding behind the door. According to his account, he then put on his prostheses and tried to kick down the locked door, striking it with a cricket bat in a panicked attempt to reach his girlfriend. Roux turned up the pressure on Vermeulen, saying the police investigator failed to properly look at another mark on the door the defence says was made by Pistorius prosthetic leg as he tried to kick it down, leaving a piece of sock fabric lodged in the wood. The defence lawyer also indicated that police investigators might have left a shoe print on the door, the door itself might have been kept in a policemans office and not in proper evidence storage, and missing fragments from the door werent examined. Vermeulen said the door was kept in a "body bag." In an evidence photo, a faint footmark on one of the door panels could be seen. "It looks like a police shoe print," Vermeulen said. "How did that come about?" Roux asked. Vermeulen said he did not know. Earlier, Vermeulen also said a metal panel on the wall of the main bathroom in Pistorius home had been damaged by being hit with a "hard" object. The panel was new evidence. A photo of the damaged plate was shown. Pistorius faces a possible life sentence if convicted of murder for killing Steenkamp. The judge, who watched the demonstrations Wednesday, will ultimately decide on the verdict. There is no trial by jury in South Africa.

And for two innings, they showed callous disregard for his fastball -- the only pitch the St. Louis Cardinals right-hander could throw without pain. Andre Ethier and three of his Los Angeles teammates hit RBI doubles during a six-run second inning Saturday en route to a 9-1 victory, enabling Zack Greinke to become the third NL pitcher to reach double digits in wins. "I think everyone could see that Lynn was just getting the fastball across," Ethier said. "And when a guy can only do that and isnt having any luck with anything else, I think its a sign for a hitter to look for a straight heater, dead-red, and wait for that pitch over the plate." Greinke (10-4) allowed a run and four hits over seven innings, struck out 10 and did not walk a batter as the Dodgers won for the 11th time in 15 games. The 2009 AL Cy Young Award winner is 13-2 with a 1.98 ERA in 19 starts following a Dodgers loss since signing a $147 million, six-year contract in December 2012. Lynn (8-6) lasted just two innings and was charged with seven runs, nine hits and two wild pitches. He is 2-4 with a 3.90 ERA in six starts since throwing his first professional shutout May 27 and beating the Mets 6-0 with a career-high 126 pitches. "Honestly, I have blister problems every time I start, but I usually dont have them rip off like they did today," Lynn said. "Im missing a lot of the top part of my finger -- the whole tip, pretty much. I think it dried out, coming from Colorado, and it just ripped off. The wetter it got today, the more it kept going back. But thats a part of pitching. You try to get through those things, and I wasnt able to do that." Los Angeles got an unearned run in the first after back-to-back infield hits by Yasiel Puig and Hanley Ramirez, who returned to the lineup after missing four games with a sore right shoulder. Puig went to third on a fielders choice grounder by Adrian Gonzalez and continued home when shortstop Daniel Descalso dropped the ball on the exchange from his glove to his right hand. The Dodgers, who didnt get an extra-base hit in the first two games of this series, broke it open during Lynns 45-pitch second inning with the doubles by Ethier, Justin Turner, A.J. Ellis and Dee Gordon. Gonzalez and Matt Kemp addded two-out RBI singles.dddddddddddd "If I threw anything else but the fastball, it hurt. It was burning," Lynn said. "But Im a fastball pitcher, anyway, and they were ready for it. I tried to throw some other pitches, but I just didnt have any feel with it." The defending NL West champs sent 11 batters to the plate during their most productive inning of the season -- including Miguel Rojas, who came in as a pinch runner after Turner strained his left hamstring running out his double. "I think we needed a good offensive showing for Zack because of how well hes done for us," Ethier said. "Hes had a couple of tough losses lately, so it was good to put up some early runs for him and let him do his work." Greinke became the first Dodgers pitcher to reach double digits in wins before the All-Star break since 2007, when Brad Penny started 10-1 and finished 16-4. Matt Carpenters third-inning homer accounted for St. Louis run. The defending NL champions tried to get back in the game in the fifth, but Greinke struck out Carpenter with runners at second and third. During the Dodgers big rally, one of Lynns pitches missed Greinkes head by inches after he squared to bunt. Gordon tried to score from second on a wild pitch to Ramirez, as Yadier Molina jogged back to the screen to retrieve it. But the six-time Gold Glove winner got the ball to Lynn in time for the tag on Gordon. "Hes always trying to take the extra base, so youre always aware," Lynn said. "I didnt think that he would do it, but youve always got your eye on him just in case. I dont even know if I would have gotten three outs that inning if it werent for that one." NOTES: Rojas replaced Ramirez at SS in the third inning and Juan Uribe took over at 3B for Turner. Uribe drove in the Dodgers final two runs with a bases-loaded single in the eighth. ... Greinke has made 121 starts since committing his last error on July 16, 2010, for Kansas City. The 11-year veteran has never won a Gold Glove. ... Lynn got a victory in relief against the Dodgers in the opening game of last years NL championship series and won Game 4 in a starting role. ...
