Another big-name prospect is coming to the big leagues as a September call up, as the Los Angeles Dodgers are promoting shortstop Corey Seager today, according to CBS Sports' Jon Heyman:

Seager, the younger brother of Mariners third baseman Kyle Seager, was the Dodgers' first-round pick, 18th overall, in the 2012 draft and a consensus top 10 prospect in baseball entering the season.

He hit .292/.343/.486 with 18 home runs and 36 doubles between Double-A Tulsa and Triple-A Oklahoma City as a 21 year old. The majority of his action came with Oklahoma City, where he hit .276/.331/.450 with 44 extra-base hits in 416 at bats, all from the left side of the plate.

Veteran shortstop Jimmy Rollins has started 119 games at shortstop for the Dodgers this season, hitting .222/.276/.358 with 13 home runs, but he is 36 years old and a free agent after this season, meaning Seager will likely take the reins at shortstop full time for Los Angeles starting in 2016, though a call up now means that he would have to stay in the minors for about six weeks next season if the Dodgers wish to gain another year of team control with him.

The Dodgers also have a need for Seager in the short term. With both Jose Peraza and Kike Hernandez injured, Rollins was the only healthy shortstop on Los Angeles' roster. It is yet to be seen whether Seager will be put into the lineup right away or serve primarily as Rollins' backup for the remainder of 2015.

Importantly, if Seager does have a strong September and was on the Dodgers' 40-man roster prior to the month beginning, so Los Angeles could put him on its postseason roster if he performs well in September, meaning that the year of the prospect could carry into October.
