60' 6" vs 43 feet - 95 MPH vs 70 MPH. Plus the BB pitcher has to have his foot on the rubber, softball pitcher is no where near the rubber when she releases - however - I wouldn't want to get hit by either - kinda of like getting hit by a 30.06 round which leaves a small entry but goes through you, or hit by a big ol' .45 round which is slower, but knocks you on your ass and leaves a lot of damage inside.
Major League Baseball stars would often take their hacks at Eddie Feigner when he was in town for an exhibition. On one memorable day in 1967, a talented row of All-Stars that included Willie Mays, Willie McCovey, Brooks Robinson, Maury Wills, Harmon Killebrew, and Roberto Clemente assembled to face the softball star. Feigner struck out all six of them. The big leaguers scarcely hit a foul ball off The King's pitches. More importantly to Feigner, the baseball stars at the time were making about $100,000 a year, and that was about what his barnstorming team was bringing in each month.
Ah but Eddie was a guy. Of course he struck out some of those guys. Put a girl out there and see what happens. Meet Jennie Finch:
