Yup. In fact, I'd venture to say that defense is the area that sabermetrics has made the biggest strides in since Moneyball came out.
I imagine most people here didn't know that the Cubs used to have agreements with some junior colleges to have exclusive access to their amateur TrackMan data so that they could get a better grasp on amateur fielding analytics before these guys were even in the minors. [MLB changed the rules as of 2020 to make these exclusive arrangements void, and all amateur data is now shared].
Teams are using all of this data to get far, far more accurate insights into players defensive qualities. Reaction time, sprint speed, pathing accuracy, etc... And that data is cross referenced with exit velocity and launch angle and even wind speed.
Twenty years ago, our best approximations of defensive quality were something akin to "on average across MLB, most guys would get 'x' number of outs on 'y' opportunities. This player made a few more outs on a similar number of opportunities, so he must be pretty good."
The improvements in defensive quantification have been frankly incredible. It's no surprise that smart teams have been able to make some serious headway with all this new information.
