LOS ANGELES -- Dodgers shortstop Corey Seager will undergo an MRI exam on his right leg on Saturday to determine whether he suffered a hamstring strain or merely a cramp during Friday night's 6-1 win over the Rockies.

He said he's "pretty confident" this injury will not put him on the disabled list, "but you never know. Tomorrow, the second day is always when you really know. I don't know now."

Seager left the game at the end of the second inning. He said he felt something on the swing and on his first step out of the batter's box during his two-out RBI single, and again when he took an awkward step as he advanced to second base on the throw. He remained in the game and scored from second on Justin Turner 's single, but the 23-year-old went straight from the dugout to the clubhouse with a trainer.

"It tightened up and felt more like a cramp than anything, and coming around third, there was no point to push it," said Seager. "I've had a bunch in the past and I know when it's not really bad. It was one of those that could have loosened up easily. Coming around third, I could have stayed in. I've done that in the past and made it way worse."

Seager said he's had four previous hamstring injuries, two in each leg, partially tearing his left hamstring and dealing with moderate strains the other three times.

Seager, the Dodgers' All-Star candidate at shortstop, is hitting .298 with 12 homers and 39 RBIs with a .909 OPS. He was an All-Star last year, when he was the unanimous National League Rookie of the Year.

Seager was replaced at shortstop by right fielder Enrique Hernandez , with Yasiel Puig taking over right field.
