Aaron: 6,4
Dick Allen: 3,2

BOLD: highest

Red: lowest; for AB/HR lowest is fewest AB to homer, the best

OPS+ On Base average Plus Slugging average adjusted for years and ballparks
100*[OBP/lg OBP + SLG/lg SLG - 1]
Adjusted to the player’s ballpark(s)

BA -- Batting Average: Hits/At Bats
For recent years, leaders need 3.1 PA
per team game played

OBP -- On Base "Percentage" (really average) (H + BB + HBP)/(At Bats + BB + HBP + SF) For recent years, leaders need 3.1 PA per team game played

SLG -- Slugging average: Total Bases/At Bats or
(1B + 2*2B + 3*3B + 4*HR)/AB
For recent years, leaders need 3.1 PA
per team game played

PA -- Plate Appearances
When available, we use actual plate appearances from play-by-play game accounts
Otherwise estimated using AB + BB + HBP + SF + SH,
which excludes catcher interferences.
