Slugging average >= .700 qualified on Total Bases. Then add Sacrifice Flies to At Bats and four dropped below .700.

Precedent:

Hornsby (twice), Cobb, Heilmann, Terry lose .400 Batting Average when adding Sacrifice Flies to At Bats.  Monday, May 26, 2025

...sacrifice flies were counted in 1908–1930 and in 1939 but inseparably from sacrifice hits; thus a batter who advanced a runner to any base while being retired himself would be spared an at bat. For purposes of his batting average his sacrifice would be chalked up as a non-event, like a walk...

For 1940–1953, however (as in the years 1931–1938) sacrifice flies were counted as outs, even though they registered as RBIs. Ever since 1954 sac flies were once again accounted in batting average as non-appearances (like walks) and as RBIs...

Finding their SF turns out to be pretty easy. (Example Babe Ruth)

For single seasons, Playing in the AL or NL, in the regular season, requiring Total Bases >= 300 and Slugging Percentage >= .700, sorted by descending Slugging Percentage.

Instead of making the requirement AB or even worse PA, make it the numerator: Total Bases (TB).

It's an elite list. Missing are Mays, Aaron and DiMaggio.
