Dodgers lose Matt Kemp for at least four weeks this time

Head trainer Sue Falsone explains on a short Dodgers video that outfielder Matt Kemp, just back from a hamstring muscle strain, has reinjured the area of the first injury and has a second strain as well. Both are grade one strains, she said, meaning they are at the less severe end of the scale. Data from other players calls for a "best case" return to play in four weeks, she said. He missed two weeks earlier in May with the first hamstring strain. He'll take longer to rehab this time because it's a repeat injury and there are two strains.

On the video you see Kemp looking a bit lame as he ran the bases during Wednesday night's game. In the dugout he breaks a bat over his thigh in frustration at being hurt again. Until the first injury he was among the league's leaders in several hitting categories, including home runs. It's starting to look like he may not play enough games to have a Most Valuable Player-level season, as the fans have been chanting at Dodger Stadium.
