On the diamond, I had been rough on Babe. I'd never taken my spurs out of his hide and one day he'd come looking for me in the Detroit clubhouse with fistic mayhem in mind. We'd won and lost duels to each other way back since 1915, when Babe had been a rookie pitcher with Bill Carrigan's Boston Red Sox.
