I agree it's a very SSS and if Sano didn't have a history of this exact problem, I would ignore it completely.
But it's a little unsettling to see a player of his capability and age striking out that often against MiLB pitchers.
It could be nothing more than statistical noise in a SSS but I don't like seeing it.
Compared to the 2018 team, the 2019 Twins also look like a roster that can better absorb a high strikeout bat. Not only are many of the biggest offenders last year either gone or marginalized, but nearly to a man, everyone on the team is striking out less this year. Maybe some of that will rub off on Sano as well.
Oddly, Nelson Cruz seems to be the only batter that is striking out more this year.
