We can see that Adam Eaton led the way in 2016 with 11 Runs Saved due to his arm—9 saved in right field and 2 saved in center—followed by Starling Marte and Colby Rasmus with 9.
Let's examine the leaders in both Outfield Kills and in preventing runner advancements. It is important to look at the players with the lowest XBT% for each outfield position because a runner is less likely to take an extra base when a left fielder, who is closer to third base, fields the ball. The left field positional average for extra bases taken is only 37 percent, as opposed to 55 and 47 percent for center field and right field, respectively.
