The younger brother of Mariners All-Star third baseman, Kyle Seager, Seager was ranked baseball's No. 2 overall prospect, according to MLB.com's midseason updated rankings. Seager made his Major League debut with Los Angeles this evening, batting eighth and playing shortstop.
The 21-year-old Seager was drafted in the 1st round (18th overall) by the Dodgers in the 2012 MLB Draft and has progressed quite quickly through the minor leagues.
After he posted a monster .349/.402/.602 line (526 PA) in High-A and Double-A ball last year, Seager's name began to be thrown around as one of the best prospects in the minor leagues. He shared the Dodgers' minor league player of the year award that year with current Los Angeles center fielder Joc Pederson.
So far this year, Seager has performed quite well in the upper levels of the minor leagues, hitting .292/.343/.486 in 545 plate appearances between Double- and Triple-A.
It's hard to know exactly what impact Seager will have on the Dodgers from the get-go. He was called up as shortstop depth behind Jimmy Rollins, as fellow prospect Jose Peraza has reportedly been dealing with a sore hamstring and will miss three to five games.
Seager's cup of coffee in the Major Leagues allows the Dodgers to see if they believe he is ready for the MLB full-time next Opening Day as well.
Overall, according to MLB.com, Seager is quite a well-rounded prospect. On the 20-80 scouting scale, he does not have one specific tool that quite pops out. Rather, Seager's tools rate in the 40-60 range and overall MLB.com believes he is a 70 (well above average player).
