Spring training at bats aren’t equivalent—hitters and pitchers aren’t approaching an at bat as they do in the regular season. But it’s no matter as we’re going to need to see a lot more plate appearances before the stats would be reliable indicators. Fangraphs[0] has a good guide to sample size. Slugging, for example, isn’t stable until 320 at bats. We’ll check back in mid July or so.
Also, we haven’t given pitchers a chance to adapt. Perhaps pitching outside (now a thinner part of the bat) will take the force out of the hit leading to softer contact.
