An MRI on Matt Kemp‘s left hamstring revealed a strain, and the Dodgers center fielder is day-to-day. Tony Gwynn Jr. is starting in center field and Kemp was listed as available if the Dodgers need him to pinch hit. Kemp has played 399 consecutive games, the longest streak in the major leagues.

Kemp did not take part in pregame activities Monday — the team stretched and took batting practice without him — which only reduces the likelihood of his appearing in tonight’s game.

However, the Dodgers might need him.

Their bench was shortened by one when Juan Uribe reported soreness in his left wrist prior to the game, and the third baseman was placed on the 15-day disabled list.

Dodgers manager Don Mattingly said that Uribe’s wrist ailment is related to the one that forced him to miss four games in April. Uribe is hitting .250 with one home run and 10 RBIs. He hit his first home run of the season Friday against the Colorado Rockies.

Infielder/outfielder Elian Herrera was recalled from Triple-A Albuquerque and added to the 40-man roster to take Uribe’s spot. The Isotopes are playing in Salt Lake City and it’s unclear whether Herrera would be at Dodger Stadium in time for tonight’s game. For what it’s worth, the switch-hitting 27-year-old was listed as available on the roster sheet in the Dodger dugout.

Herrera was hitting .358 with two home runs and 14 RBIs at Triple-A, with nine stolen bases in 28 games. Dodgers coach Manny Mota described Herrera as a “prototypical leadoff hitter” who can play multiple positions. More on him in tomorrow’s editions.

To make room for Herrera, the Dodgers designated Trent Oeltjen for assignment. Oeltjen was hitting .218 for the Isotopes with no home runs and three stolen bases. The 29-year-old from Australia hit .220 over parts of three seasons with the Dodgers and Diamondbacks.
