Colorado Rockies franchise cornerstone Nolan Arenado and Oakland Athletics third baseman Matt Chapman each won a Rawlings Platinum Glove Award as the top defender in their respective league. Established in 2011, a fan vote results in one player from the National League and American League receiving a Platinum Glove.
The winners are determined by combining votes based on an adjusted SABR Defensive Index for each of the nine Rawlings Gold Glove Award winners in each League and votes from fans. Los Angeles Dodgers All-Star and MVP candidate Cody Bellinger, who won a first career Gold Glove Award in right field, was therefore among the finalists for the top defensive honor.
