Does Eric Davis Have The Highest Power-Speed# Ever For A 162 Game Span And Is It By A Wide Margin?

Here is the definition Power-Speed# from Baseball Reference:

"2 x (Home Runs x Stolen Bases)/(Stolen Bases + Home Runs) The harmonic mean of HR and SB. To do well you need a lot of both. Developed by Bill James."

Stathead, BR's searchable data base, has a new feature called "Span Finders." So you can find, say, all the spans of 162 games when a player hit at least 50 HRs. 

Davis had a span of 162 games covering part of 1986 and part of 1987. From June 18, 1986 thru July 10, 1987 he hit 49 HRs and stole 93 bases. His AVG-OBP-SLG were .306-.405-.629. He got caught stealing just 11 times. Links to the search results from Stathead are listed at the end (the search where I found this feat by Davis called for 162 game spans with 40+ HRs and 90+ SBs).

Even if we lower the cutoff to 35+ HRs and 85+ SBs, Davis is still the only guy to make the list. If you go to 30/80, only Rickey Henderson also makes it. At 40/60, Davis is the only guy.

A search for guys with 50/40 turns up only Ronald Acuna and Barry Bonds. The table below shows some of the other top cases along with Davis's. Some hypothetical cases are also shown.

Player	HR	SB	PS#
Davis	49	93	64.18
Acuna	51	43	46.66
Bonds	50	43	46.24
Henderson	34	93	49.80
Henderson	30	104	46.57
Hypo1	40	162	64.16
Hypo2	45	112	64.20
Hypo3	80	20	32.00
Hypo4	70	40	50.91

The hypothetical cases are listed so you can see how high the numbers would have to be to get close to Davis or how far below Davis some really good cases are. If a player had 40 HRs, to just about match Davis he would need 162 SBs. Obviously no one did that.

At 64.18, Davis is very well above the next highest cases that I could find. I did not find any other cases even reaching a score of 50. Maybe they are out there and I just did not do the right search.

There were no 80/20 cases and no 70/20 cases

These links will take you to some of the searches I did.  (50/40) means 50+ HRs and 40+ SBs.

(50/40)
(40/90)
(40/80)
(40/70)
(40/60)
(30/80)
(20/100)  (Only Ricky Henderson made this list, his 30/104 case in the table above)
