Matt Kemp is listed by Dodgers as day to day After Matt Kemp insisted a day earlier that he did not want to be placed on the 15-day disabled list, the Dodgers did just that Monday night because of Kemp's sore left hamstring. "We just feel it's the right thing to do," Manager Don Mattingly said of his center fielder. We've got to get this thing healthy and healed up. The announcement came after the Dodgers defeated the Arizona Diamondbacks, 3-1, at Dodger Stadium, a game Kemp sat out. The Dodgers also said they called up outfielder Jerry Sands from triple-A Albuquerque. The move ended Kemp's streak of 399 consecutive games played, which was highest among active players. "I'm very disappointed," Kemp said. I want to be out there with my team playing. But I need to get my leg better. Kemp initially hurt his hamstring May 5 in Chicago but kept playing last week, and he irritated the injury while running out a grounder Sunday. An MRI exam Monday confirmed the strain. "You've just got to let [hamstrings] heal, and it's going to take some time," Kemp said. Kemp was baseball's hottest hitter in April, batting .417 and slugging 12 home runs. But in May he has batted .212 with no homers. Uribe also on DL Third baseman Juan Uribe was put on the 15-day disabled list after his sore left wrist worsened. Adam Kennedy started Monday's game in Uribe's place. At the same time, the Dodgers purchased the contract of utility player Elian Herrera from triple-A Albuquerque. Uribe, 33, was batting .250 in 25 games with one home run and 10 runs batted in. His sore wrist first came to light nearly a month ago when the Dodgers were in Milwaukee playing the Brewers. "It sounds like that within the next 24 hours they're going to be getting an MRI [exam] on this wrist and get more information and go from there," Mattingly said. "Hopefully, it's something that's not major and it is two weeks [on the DL] and he's back out there, because he's played well for us," Mattingly said. He's swung the bat well, he's played good third base, we're a better lineup when he's out there. The switch-hitting Herrera can play several positions, and he was batting .358 for Albuquerque with two home runs and 14 RBIs. "He's played center field, he's played right, he's played left, he's played second, short, third and it sounds like he's been good everywhere," Mattingly said. To make room for Herrera on the team's 40-man roster, the Dodgers designated outfielder Trent Oeltjen for assignment. That typically means Oeltjen would be put on waivers and, if he goes unclaimed, the Dodgers would have 10 days to trade him, send him to the minors or release him.
