Seager is a consensus top-10 prospect and you could argue that he is the top prospect in all of baseball. The 21-year-old has split time between Double-A and Triple-A in 2015 and has posted some solid numbers, hitting .292 with 18 homers and an OPS of .829 in 124 games.
Seager has come up through the system as a shortstop, but with the Dodgers looking for him to become more versatile, he has played 19 games at third base. It will be interesting to see how much Seager plays down the stretch with Jimmy Rollins starting at shortstop and Justin Turner playing nearly every day at third base.
Rollins has not been playing like he has in his career, however, in 2015. The veteran shortstop has only hit .222 with a .276 OBP, which are the lowest numbers he has posted in his career. If Seager gets a chance at shortstop, he could take it and run if he can produce better than the 36-year-old. This could be an interesting position battle down the stretch in September as the Dodgers try to hold on to a 6.5-game lead in the NL West over the San Francisco Giants.
While Seager will not be automatically eligible for the postseason roster because he was called up after the September 1 deadline, the Dodgers have five players on the 60-day disabled list, any of whom can be “replaced” on the postseason roster by any player who was in the organization on August 31.
With Seager’s call up, 18 of the top 25 Baseball America prospects have now played in the Majors in 2015.
Corey isn’t the only Seager brother now in the Major League pipeline as his brother, Kyle Seager, is a Gold Glove third baseman for the Seattle Mariners.
