Just how will Dodgers use phenom Corey Seager in final month?

The phenom is here, the Dodgers’ most prized prospect. And now that Corey Seager has arrived, what do they do with him?

They’ve said all along they did not intend to bring him up and not play him, so don’t be surprised if the left-handed infielder is in the lineup Thursday night in San Diego against right-hander Colin Rea. He won’t suddenly be playing every day, but he could see considerable action.

Seager can play shortstop and third, the two positions where the Dodgers currently have no true backup. Manager Don Mattingly has tried to limit the consecutive starts of Justin Turner at third, and Jimmy Rollins is a 36-year-old shortstop.

Rollins has started the past 18 consecutive games (.221/.338/.606) and played in the last 36 consecutive games (.262/.313/.436). He’s way overdue for a day off.

Turner was hit on the left pinkie by a pitch Wednesday night, though he finished the game and said he would be available Thursday in San Diego. Still, it could have stiffened up overnight. Plus, to protect his knees, Mattingly doesn’t like to play Turner more than four consecutive games.

With Enrique Hernandez on the disabled list, the Dodgers lost their primary backup to both positions. Rookie Jose Peraza can play short, but Fox Sports Ken Rosenthal reported Peraza is battling a sore hamstring. Apparently, it’s contagious.

The Dodgers will continue to work Chase Utley out at third, and at some point, they’re going to have to play him there to see if that’s a real possibility.

For now, though, expect Seager to get some playing time. After the four-game series in San Diego, the Dodgers go to Anaheim for three games and will need a designated hitter, offering more possibilities.

Fans have been hearing about Seager for several seasons, but it still might be best to temper expectations. After tearing up Class A and double-A last year (.349/.402/.602), he had a more modest season at triple-A (.276/.331/.450) this season.
