SO/HR, SO/BB: Harmon Killebrew, Mickey Mantle best; Lou Brock, Derek Jeter worst among Strike Out leaders.

That's among the players with the most career Strike Outs (SO): minimum 1,699.

Use common stats to judge both batters and pitchers. Monday, August 25, 2014

A couple of times during the Yankee-White Sox series just completed Yankee announcer Micheal Kay stated that Adam Dunn had the worst ratio of strike outs (SO) to at bats (AB) in baseball history.  He indicated that his teams were willing to tolerate his SO because he also hit a lot of home runs (HR).  Unmentioned was the real reason for that tolerance: Dunn drew a lot of Bases on Balls (BB).

That combined with my recently noticing that Derek Jeter was number 13 in career SO made me look at the ratios: SO/HR and SO/BB.  I also added them together as an X factor.  The lower, the better.
