I thought this might be the case as well, but when I looked it up on Fangraphs, the Twins' O-Swing% (which is the % of balls outside of the strike zone that they swing at) is actually down compared to last season (32.6% in 2019, ranked 10th in MLB vs. 30.1% in 2020, 15th in MLB). Furthermore, their Z-Swing% (which is the % of balls in the strike zone that they swing at) is WAY down compared to last season (70.8% in 2019, 4th in MLB vs. 65.9% in 2020, 23rd in MLB). Overall, they're making about the same amount of contact when they swing in 2020 vs. 2019. This suggests that they're not being aggressive enough this season since they're looking at significantly more strikes without swinging. It seems like this could be coaching related... Perhaps they've been preaching more patience at the plate this season? Although, I'm not sure why they would want to change their approach after last season's success at the plate. It could also just be that they've only played 35 games and are still honing their eyes at the plate. Or maybe it's simply a matter of more plate appearances going to more patient hitters, since free swingers like Schoop and Cron are no longer on the team.
