Adrián Beltré recorded the most defensive runs saved in Major League Baseball during the 2003–2021 seasons.
In baseball statistics, defensive runs saved (DRS) measures the number of runs a player saved or cost his team on defense relative to an average player.[1][2] Any positive number is above average, and the best fielders typically have a DRS figure of 15 to 20 for a season.[3] The statistic was developed by Baseball Info Solutions and the data used in calculating it first became available for Major League Baseball (MLB) in 2003.[4][5]
