1998 Mark McGwire: .299/.470/.752

The ratio of SLG/OBP is exactly 1.6 and the ratio of OBP/BA is 1.572. Other notable seasons include:

1999 Mark McGwire: .278/.424/.697, (OBP/BA = 1.525, SLG/OBP = 1.644)

2001 Barry Bonds: .328/.515/.863, (OBP/BA = 1.570, SLG/OBP = 1.676)

So it seems that one needs to put up historic numbers to achieve a “golden ratio” season, perhaps making them impossible in the post-steroid era. However, hope springs anew in Jose Bautista:

2010 Jose Bautista: .260/.378/.617, (OBP/BA = 1.454, SLG/OBP = 1.632)

Or, perhaps a Carlos Pena/Mark Reynolds type will achieve one in a less historic manner.

2009 Carlos Pena: .227/.356/.537, (OBP/BA = 1.568, SLG/OBP = 1.508)

2010 Mark Reynolds: .198/.320/.433, (OBP/BA = 1.616, SLG/OBP = 1.353)

The above seasons pretty much run the gamut of possible “golden ratio” lines, from historic to barely maintaining a starting role.

In case you’re interested (and if you’ve read this much you must be), the OBP/BA ratio closest to the golden ratio (1.618) is a tie between 2010 Mark Reynolds (above) and

1945 Eddie Stanky: .258/.417/.333, (OBP/BA = 1.616)

1943 Eddie Joost: .185/.299/.252, (OBP/BA = 1.616)

1988 Darrell Evans: .208/.337/.380, (OBP/BA = 1.620)

And the SLG/OBP ratio closest to the golden ratio was right on the nose (to three decimal places)

1962 Frank Howard: .296/.346/.560, (SLG/OBP = 1.618)

Less than .100 points from IsoD and IsoP (i.e., emptiest batting averages):

Ben Revere – .267 / .310 / .309 / .619

Franklin Gutierrez – .224 / .261 / .273 / .534

Chris Getz – .255 / .313 / .287 / .600

Paul Janish – .214 / .259 / .262 / .521

Juan Pierre – .279 / .329 / .327 / .656

Orlando Cabrera – .238 / .267 / .307 / .574

OBP’s higher than SLG’s:

Chris Getz – .255 / .313 / .287 / .600

Ruben Tejada – .284 / .360 / .335 / .695

Angel Sanchez – .240 / .305 / .285 / .590

Adam Dunn – .159 / .292 / .277 / .569

Jonathan Herrera – .242 / .313 / .299 / .612

Jamey Carroll – .290 / .359 / .347 / .706

Nate McLouth – .228 / .344 / .333 / .677

Juan Pierre – .279 / .329 / .327 / .656

Jason Bartlett – .245 / .308 / .307 / .615

Ben Revere – .267 / .310 / .309 / .619

Josh Thole – .268 / .345 / .344 / .689

Don’t forget Bautista’s .302/.447/.608!
