Outfielders must cover large distances, so speed, instincts and quickness to react to the ball are key. They must be able to catch fly balls above their head and on the run, as well as prevent balls hit down the right field foul line from getting past them. Being situated 250–300 feet from home plate, they must be able to throw the ball accurately over a long distance to be effective. Of all outfield positions, the right fielder should have the strongest arm, because they are the farthest from third base. Hits to right field tend to curve toward the right field foul line, and right fielders must learn to adjust to that.
