If the season were to end today, the Washington Nationals would lead the majors in fewest strikeouts. Even with the season ending in two days, this still may be the case.
For the year, Nationals hitters have fanned 424 times. Houston Astros hitters have struck out the next fewest at 426. The next closest team is over twenty strikeouts away, so the battle for strikeout-less supremacy comes down to those who played in the 2019 World Series.
On the surface this may look like a great statistic to lead the league in. Nationals hitters are going to produce outs every game, and a strikeout is an unproductive out.
