The St. Louis Cardinals were well established in 2019 for their strong defense, having an MLB-high six players nominated for the Rawlings Gold Glove Awards. Kolten Wong was the sole winner, but the only infield position without a nominee for the Cards was the third base position. This Gold Glove was won by the undoubtedly best third baseman, Nolan Arenado, who has been strongly linked with a trade to the St. Louis Cardinals.
The 2019 Cards finished 3rd in Defensive Runs Saved (DRS) and behind the Los Angeles Dodgers & Arizona Diamondbacks.
