Mattingly said he worked with Turner and center fielder Joc Pederson, who employs a similar leg kick to Turner, on their swings last year.“When (Turner) first got here, with the leg kick and everything, he was more of a low-swing type guy,” Mattingly said. “He had to get on top of the ball a little better.”The results have been obvious: Turner is squaring the ball up more often, leading to harder contact — and now a spot in the middle of the lineup.Olivera updateDodgers president of baseball operations Andrew Friedman said that Hector Olivera is estimated to miss two to three weeks from the time he strained his left hamstring Saturday, “but with a hamstring you don’t really know.”That timetable all but guarantees that Olivera will not reach the majors prior to the All-Star break.“It’s not like a wrist you can X-ray and say, ‘OK, it’s healed,’” Friedman said. “It was minor in nature, which is good, and so he’s in Arizona right now and rehabbing. When we get to the point of him not having any pain with it, we’ll ramp up baseball activity.”Olivera was peaking at Triple-A Oklahoma City at the time of the injury, slashing .387/.387/.581.“He started getting his legs under him, timing at the plate, the quality of at-bats were really good,” Friedman said. “He’s played predominantly on the right side of the infield. It’s a different throwing stroke from second than from third. Jose Vizcaino was there for a week with him, pregame doing stuff on the chalkboard, then started ramping up to playing more games at third. That was the plan until he got hurt.“All in all, the acclimation on the field and off the field, things are going really well.”AlsoRight fielder Yasiel Puig was scratched from the lineup a few minutes before game time with an open callus on his left hand. Puig has been dealing with the injury since Monday. Andre Ethier shifted to right field, and Alex Guerrero started in left field, in Puig’s absence. … Brandon League threw two scoreless innings for Triple-A Oklahoma City. … Clayton Kershaw was nominated for an ESPY award for Best Baseball Player. Voting will be conducted until the award is presented July 15. “I think it’s just, you know, a fit for right now for Donnie making the lineup,” Turner said of his new role. “I don’t look at myself as a prototypical three-hole hitter. I don’t think that’s who I am. For right now that’s what makes sense for Donnie in the lineup. I’m going to just take good at-bats just like I was hitting second or fifth or seventh or eighth.”Turner has evolved from a non-roster invitee in spring training a year ago, to a utility infielder, to the Dodgers’ everyday third baseman. At least, Mattingly has pledged to play Turner roughly five out of every seven games.The Lakewood native and former Cal State Fullerton star is entering his prime at a relatively late stage in his career. At 30 years old, he’s on a pace to set career highs in virtually every offensive category.Turner credited two things for his transformation: More regular playing time than he ever had in parts of five major league seasons with the Orioles and Mets, and some adjustments to his swing that he undertook going into his first season with the Dodgers.“Before, from day to day, I’d take different leg kicks trying to feel good,” Turner said. “In the offseason, ’13-14, that was one of my main goals, to try to get somewhere I could repeat it, have a foundation and know where I need to be.” Newsroom GuidelinesNews TipsContact UsReport an Error CHICAGO >> Dodgers manager Don Mattingly recently compared his daily lineup adjustments to rearranging the furniture in a house.Lately, two pieces of furniture have remained the same. Adrian Gonzalez has been the Dodgers’ cleanup hitter the last six games and Justin Turner hasn’t budged from the No. 3 slot since Mattingly put him there last Friday.Turner, who is leading the club in batting average, on-base percentage and slugging percentage, is a logical choice for a team struggling to score lately. His 10th home run of the season, a three-run shot in the third inning, paved the way for a 5-2 victory over the Chicago Cubs on Wednesday. The win gave the Dodgers a chance to split the four-game series, which concludes at 11 a.m. today.
