LOS ANGELES -- Dodgers outfielder Yasiel Puig felt continued left hamstring tightness trying to jog this week and remains sidelined indefinitely, manager Don Mattingly said Friday.
Puig, an All-Star last year, has played only 11 of the Dodgers' 40 games this year. He has two home runs and four RBIs. He was originally injured April 13, then reinjured April 24. He hurt it for a third time during a Minor League rehab game May 8.
Mattingly would not give a return timetable for Puig, but said most hamstring injuries last between four and six weeks. Using the May 8 date as a starting point, that would mean at least another two weeks on the sidelines for Puig. Considering he still can't jog, it's likely to be longer than that.
Andre Ethier has inherited the bulk of right-field playing time in Puig's absence and is hitting .304 with five homers and 14 RBIs.
Mattingly said Carl Crawford (one homer, three RBIs) has increased his workouts but still feels discomfort from an oblique injury he suffered April 28. Mattingly offered no return timetable for him, either. Alex Guerrero and Scott Van Slyke have picked up most of the left-field starts.
"Until they're moving around doing baseball activity, they are kind of off the radar," Mattingly said of his starting corner outfielders.
• The Dodgers made a Minor League trade of 27-year-old pitchers with the White Sox, receiving left-hander Eric Surkamp for right-hander Blake Smith, who is a converted outfielder.
