Agreed, hat was the ideal traditional lineup construction. But in the age of analytics that has been changed fairly significantly for some teams.. With every notch in the batting order getting approximately 20 more plate appearances over the season than the next one that becomes the prime consideration. For example Aaron Judge over the course of a season will have approximately 40-45 more plate appearances over the season batting second rather than third.I always thought it went:
#1 hitter = the speed guy with a decent average
#2 = the contact guy to advance #1
#3 = the best hitter in the lineup
#4 = the power guy
#5 = protection for the power guy
#6 - #9 = the rest
Speed is not that important for #1 - it's a bonus - but OBP is more important. Of course if its Kirk type speed that is an issue.
#2 in the traditional sense (which was often a fairly light hitting player who didn't striekout) is largely obsolete.
Of course a guy like Raines, Henderson, Alomar will fit at the top in past or current times. But last year, a guy like Raimel Tapia may have been considered to leadoff in the 80's, while the notion wouldn't even be considered today.
For example Aaron Judge bats 2nd exclusively. Shohei Ohtani spends half his games batting 2nd. Vlad spent a fair amount of time there in 2021 and 2022. Seems to be between #2 and #3 for the best hitter.
