Suppose that we looked for league leaders in stats that might represent three different skills:
Speed (triples, SBs, SB%)
Power (SLG, ISO, HRs, TBs, extra-base hits)
Getting on base (OBP, times on base)
What players have led their league in at least one stat from each category? Looking over league leaders lists, I came up with 11 different players who have done it at least once. I list them, showing the year or years they did it, which stats they did it in and the amount or rate for each one. Stats from Baseball Reference and the Lee Sinins Complete Baseball Encyclopedia. SB% starts with 1951 at Baseball Reference.
If you can think of any other player who might qualify, please let me know.
