Hampson had a similar Hard Hit Percentage during the months of June and July when his wRC+ was 45 and 87 respectively. More interesting, though, is that his BABIP actually dropped from .370 in August to .354 in September. That’s not a massive difference but the jump in wRC+ from 47 in August up to 119 is September is.
That’s because speedy guys like Hampson usually have a decently high BABIP no matter what they do. So it benefits them to put the ball in play and have a low K%. By dropping his K% a little over 11% from August, Hampson was able to become one of the Rockies’ most effective hitters in September.
Some changes to his mechanics, such as the much discussed toe tap, are to thank for getting back Hampson’s timing and confidence in the box.
"“You can’t have no confidence in this league, you know? You’re gonna get worn out,” Hampson reiterated."
And in September, Hampson certainly looked like a player that was back on track. While we probably should expect a little regression, as that K% isn’t gonna stay low forever, we should still feel like a wRC+ around 110 is within the realm of possibilities for Hampson in 2020.
