Hall of Fame Pitchers as Hitters, Part 2

Continuing with yesterday's subject: it occurred to me that slugging pct. is probably the best measure of comparing one player to another in hitting ability. So I did some calculations:

Top 20 Career Slugging Pct. among Hall of Fame Pitchers:
.389 Red Ruffing
.386 Bob Lemon
.382 Al Spalding
.342 Walter Johnson
.319 Amos Rusie
.319 John Clarkson
.310 Clark Griffith
.306 Burleigh Grimes
.301 Dizzy Dean
.301 Bob Gibson
.300 Kid Nichols
.297 Mickey Welch
.295 Don Drysdale
.287 Catfish Hunter
.287 Warren Spahn
.285 Ted Lyons
.285 Early Wynn
.282 Cy Young
.281 Hoss Radbourn
.280 Chief Bender

And the 10 worst (among those with 500+ AB's):

.116 Sandy Koufax
.134 Nolan Ryan
.157 Don Sutton
.159 Lefty Gomez
.161 Red Faber
.164 Gaylord Perry
.186 Vic Willis
.188 Addie Joss
.198 Dazzy Vance
.200 Whitey Ford

Notice that the 3 worst are all post-1950.
Of the best 8, Bob Lemon (1941-58) is the most recent.
I should have mentioned Walter Johnson's hitting prowess in the earlier post. Among his highlights: .235 avg., 255 RBI's, 94 doubles, 41 triples and 24 homers (in deadball era!) in 2324 AB.
