Dodgers Send Kemp Back to D.L. With Hamstring Strain The Los Angeles Dodgers have placed center fielder Matt Kemp on the 15-day disabled list for the second time this month because of a left hamstring strain. The move came Thursday after Kemp went 1 for 4 with a double and a run scored in two games since being reinstated from the disabled list two days earlier. Kemp left Wednesday night's game against Milwaukee after scoring all the way from first base on a first-inning double by Andre Ethier. He is batting .355 with 12 homers and 28 runs batted in over 36 games. HAFNER HAS SURGERY Indians designated hitter Travis Hafner had surgery on his right knee and could be sidelined six weeks. Hafner was placed on the 15-day disabled list Wednesday. Cleveland, however, said he would need at least one month to recover from the operation, which was to clean up frayed cartilage. MARKAKIS HEADING TO D.L. Orioles outfielder Nick Markakis has a hamate fracture of his right wrist and will undergo surgery on Friday. The injury is believed to have occurred more than a week ago when Markakis slid into a base. He aggravated his wrist injury during his final at-bat Tuesday in Toronto. The typical recovery time from this kind of surgery is three to four weeks. This will be the first trip to the disabled list for Markakis, who has never played in fewer than 147 games in a season since coming into the league in 2006. TULOWITZKI IS OUT The Colorado Rockies have placed shortstop Troy Tulowitzki on the 15-day disabled list because of a left groin strain. Tulowitzki felt pain after running out of the batter's box when he grounded out to second base during the Rockies" six-run sixth inning against Houston on Wednesday. He left the game after that. He underwent a magnetic resonance imaging test on Thursday, and the team was awaiting the results. MANAGER SUPPORTS CLEMENS Phil Garner, Roger Clemens's manager for two and a half years with the Houston Astros, became the latest witness to speak glowingly of Clemens's leadership and work ethic at his federal perjury trial in Washington. The testimony is part of the defense's effort to portray Clemens as an athlete who achieved success late in his career through hard work, intelligence and unrivaled intensity. Prosecutors say he used steroids and human growth hormone to help prolong his career. Ever see Roger Clemens cut corners? Clemens's lawyer, Rusty Hardin, asked Garner on Thursday. "Never did," Garner replied. JUDGE APPROVES METS DEAL The settlement proposed in mid-March to end the litigation against the Mets" owners, Fred Wilpon and Saul Katz, received the approval of the judge overseeing the case. Wilpon and Katz were not in the courtroom. Under the settlement, Irving H. Picard, the trustee for the victims of Bernard L. Madoff's Ponzi scheme, dropped claims that Wilpon and Katz willfully ignored signs that Madoff might have been a fraud during their many years of investing with him.
