Enrique Hernandez could be out for weeks with hamstring strain

LOS ANGELES -- The Los Angeles Dodgers diagnosed utility man Enrique Hernandez with a Grade 1 strained left hamstring and manager Don Mattingly acknowledged it will likely be at least "a couple of weeks" before Hernandez can play again.

The team had not yet put Hernandez on the 15-day disabled list Monday afternoon, but Mattingly said that remains a possibility before game time.

The most troubling aspect for the Dodgers is the recurrence of hamstring injuries. Yasiel Puig has twice been on the DL for hamstring injuries and could be out until the eve of the playoffs with his current injury. Howie Kendrick has been out since Aug. 9 with a hamstring injury. That's three of their best right-handed hitters shelved by the same injury. Kendrick's recovery has plateaued and a rehab assignment has been pushed back at least several days.

Mattingly said the Dodgers' medical staff is undergoing an internal review to "evaluate themselves and make sure they're not missing anything."

"I've been with different teams over the years and, sometimes, it's the obliques. This year, for us, it's the hamstring," Mattingly said.

Losing Hernandez makes it difficult for the Dodgers to spell slumping center fielder Joc Pederson, who has managed just five base hits in his last 60 at-bats though he has walked 21 times (and struck out 27) in that span. Mattingly said the team is contemplating using speedy second baseman Jose Peraza at times in center field. He has played there in the minor leagues.

Meanwhile, the first wave of September call-ups will arrive Tuesday. Reliever Joel Peralta will come off the DL and pitchers Ian Thomas and Mike Bolsinger and catcher Austin Barnes will all be recalled. Mattingly said that will be it for the first wave, but he said the team hasn't ruled out promoting either of its top prospects, Julio Urias or Corey Seager, both of whom now are in Triple-A after Urias was promoted Monday.
