CHATTANOOGA. Tenn., April 3. —Virnie Beatrice Mitchell—Jackie when she's on the diamond, hria made a debut in organized baseball that many masculine hutters might envy. The only woman pitcher in organized baseball struck out Babe Ruth and Lou Gehrig in succession when the Chattanooga Lookouts met the New York Yankees and then walked Tony Lazzeri to complete her mound dutv. But a “catch’’ was seen in the act when the Babe politely tipped his hat when he came to bat, swung wildly at a couple of pitches that fans thought he might have hit easily and let the third go past for a called strike. And Lyn Lary, on first base, did not try to steal white Jackie took a long windup.
