LOS ANGELES >> The Dodgers have been gushing about Corey Seager for a while.After all, Seager was their first-round pick in the 2012 draft and came into this season as the consensus No. 1 prospect in baseball and a leading contender to win the National League Rookie of the Year Award."There's really nothing he can't do on the baseball field -- the at-bats, the late-inning production, playing a premium defensive position, hitting the ball out of the park, driving in runs, taking a walk when he needs to, running the bases," Dodgers manager Dave Roberts said recently of his rookie All-Star.
