I think he’s acceptable vs RHP based on the data available to start the season. If that was the correct decision a week ago, it’s still the correct decision.
As that data grows, especially as we see how Albies adjusts, the conclusion may change. The data from 20 PAs isn’t enough to draw another conclusion though.
If someone said, “Albies is going to be the lead off hitter for the next 5 years, we think he is on the verge of figuring it out, so he may as well hit lead off now”, that would be a defensible argument.
When someone says, “Albies had a good game last night, so that means he is likely to have a good game tonight, and should be leading off”, that isn’t a logical argument to make.
