Perhaps the most overlooked player on the 40-man roster is infielder Ildemaro Vargas. After washing out of the Cardinals system by 2014, Vargas played 30 games for the Bridgeport Bluefish before being signed by the Diamondbacks in 2015. Vargas was assigned to the Class A Kane County Cougars and hit .321/.385/.438 in 86 games. Vargas was 2 years older than the average player in the Midwest League, so you expected dominance. In 2016, the Diamondbacks gave him an aggressive assignment to AA Mobile, where he .276/.325/.372 with fantastic glovework at both SS and 2B that earned him Southern League All-Star honors.
