Still ignoring the career .864 OPS in Triple A, I see
Everyone hits in the PCL. Here's the list of players that year who had a higher OPS than Kieboom's .902 in 2019 (minimum 350 ABs):
Yadiel - 1.010
Matt Reynolds - .922
Jose Mamolejos - .911
Andrew Stevenson posted a .886 OPS that year as well in Fresno.
For a more complete comparison:
Stevenson: .334 / .383 / .503
Kieboom: .303 / .409 / .493
