Which is OK, he's 20.
His growth curve is scheduled to get another bump in October when Seager joins three other Dodgers prospects in the Arizona Fall League.
The league is designed for players considered serious major league prospects who played at the double- or triple-A level, but Seager was also at the AFL last year as a high-level prospect invite from Class A. Teams are allowed to send two such prospects.
Seager struggled last season as a 19-year-old, hitting .181 with two home runs and three doubles in 19 games. He is regarded as the Dodgers' top prospect by MLB.com and the team's No. 2 prospect (behind Joc Pederson) by Baseball America.
Scheduled to join Seager on the Glendale Desert Dogs are outfielder Scott Schebler, infielder Darnell Sweeney and left-handed reliever Michael Thomas.
Seager, 6 feet 4, split time this season between Class-A Rancho Cucamonga and double-A Chattanooga. He leads the Lookouts in hitting (.350), after batting .352 with two home runs, 34 doubles and 18 runs batted in in 80 games for Rancho Cucamonga. He was selected most valuable player in the California League.
Because os his height, some predicked the Dodgers would move him to third base after taking him with the 18th overall pick in 2012, but that hasn't happened yet.
Schebler, the Dodgers' minor league player of the year last season, is hitting .283 and leads the Southern League in home runs (27) and triples (14).
