Matt Kemp had just finished smacking several balls over the fence during batting practice ahead of the Dodgers’ game against the Colorado Rockies on Tuesday. The sweetness of his swing and the power with which it zoomed through the zone was something to see.Kemp was the toast of the Dodgers in 2011, when that swing helped create a marvelous season where he walloped 39 home runs, drove in 126 runs and scored 115 times — all league highs. He also batted .324, slugged .586, had an OPS of .986 and stole 40 bases. He finished second in National League MVP voting and came close to winning the elusive Triple Crown.Afterward, Kemp signed an eight-year contract worth $160 million.Three years later, Kemp is still trying to regain that magic. Hamstring and shoulder injuries in 2012 limited him to 106 games, during which he hit .303 with 23 home runs and 69 RBIs. Hamstring and an ankle injury reduced him to just 73 games in 2013, when he hit just .270 with six home runs and 33 RBIs. “Well, I was locked in,” he said of 2011. “Body-wise, I was feeling all the way 100 percent. You know, it’s just a different year. Every year is different. Everybody’s got stuff they’ve gotta deal with and mine the past years have been injuries I’ve had to overcome and it’s getting better and better every day.”It must be difficult, Kemp was told, to be a superstar one year and then suddenly become something other than that. Kemp agreed, but he wasn’t singing the blues about it. Rather, he spoke with a stiff upper lip.“It’s tough,” he said. “I think it’s tough for anybody to try to go from being something to being something else and you’re trying to get back to where you were. Sometimes injuries take time to heal. It could be one year, two years, three years. But for me, every year I’ve had to deal with a different injury.“There was my shoulder and my ankle, so those are two major body parts, especially for the game of baseball, especially for what I can do as far as hitting home runs and stealing bases. I’ve just gotta get my legs under me and work every day to get back to where I was before.”Kemp had offseason left shoulder surgery following 2012 and offseason left ankle surgery following the 2013 campaign.“I feel good,” he said of those repairs. “There are times when I’m stiff, sore and that’s just any baseball player. You can ask any baseball player, something’s always hurting on him.”As far as getting back to what he once was, Kemp has no doubt he will.“Oh, I’m not worried about it,” he said, emphatically. “I know I’m going to be back to where I need to be as far as stealing a lot of bases and hitting home runs, driving in runs. I’m going in the right direction now.”Manager Don Mattingly also believes fans will again see the Kemp of 2011.“I’m confident,” Mattingly said. “It’s still there. He’s swinging the bat good. He looks good.”Guerrero still outAlex Guerrero’s agent said the infielder is still undergoing outpatient skin-graft treatments on his left ear and could be two weeks away from resuming baseball activities.Guerrero hasn’t played since May 20, when a portion of his left ear was bitten off by then-teammate Miguel Olivo during a game with Triple-A Albuquerque. He was hospitalized for several days after the incident and needed surgery to re-attach the ear.“We can safely say the surgery is fully successful,” said Guerrero’s agent, Scott Boras.Two weeks from today is July 1, exactly six weeks after the incident. Guerrero hasn’t been able to work out, run, or throw in the meantime. Guerrero could face another lengthy process as he returns to baseball shape. This and thatMattingly said third baseman Juan Uribe (hamstring) continues to improve and will soon be ready for a rehab assignment — perhaps this week. … Crawford (ankle) still can’t run or hit and has seen the team physician this week. … Third baseman Justin Turner (calf) could be ready to play in the next series beginning Friday in San Diego.— Staff writer J.P. Hoornstra contributed to this report Newsroom GuidelinesNews TipsContact UsReport an Error Things have changed so much for Kemp that this season he lost his center-field spot to Andre Ethier and the only reason he has been playing every day is because left fielder Carl Crawford is on the disabled list.Well, don’t look now, but Kemp just might be flirting with becoming the player who shook up the baseball world in 2011.“I feel good, just trying to have good at-bats and trying to get good pitches to hit, trying to grind it out and just get in a groove,” he said during an exclusive interview with this newspaper.Kemp, just 29, is batting .267 with six home runs and 24 RBIs in 217 at-bats. Nothing to write home about. But over his past 10 games, he is 14 for 33 — an average of .424 — with a home run and eight RBIs. He has gotten two hits in four of his past five games.He was asked to talk about how he feels at the plate right now compared to how he felt in 2011.
