As part of a tradition that has existed for numerous decades Topps has named their 2016 MLB All-Star Rookie Team, and it includes three Dodgers' players -- Corey Seager, Julio Urias and Kenta Maeda. No doubt this is a testament to a flourishing minor league system. Per a Topps release:
The Topps All-Star Rookie Team began in 1959. The winners also receive a gold “cup” on their official Topps baseball card in the 2017 set, which has been a tradition for many years.
...The Topps MLB All-Star Rookie Team – nicknamed the Topps Rookie Cup – is awarded to one player for each position, a right-hander starter, a left-handed starter, and a relief pitcher.
