The Nationals are in the midst of rebuilding their pitching staff. Last season, the team was second to last in the league with a 5.35 ERA, trailing only the Colorado Rockies. There are many steps that the team will need to take to improve their pitching, but one potential fix is diversifying their team's pitching arsenal by throwing more splitters.
A splitter is a type of off-speed pitch where a pitcher will hold the ball with their fingers spread in a V-shape around the horseshoe of the seams. The pitch is slower than a fastball and has late downward movement to induce hitters to chase and swing and miss.
