- December 5, 1940 - Paul Waner was released by the Pirates. The Hall of Fame OF’er played 15 seasons in Pittsburgh, hitting .340 with 2,868 hits, 1,627 runs and 1,309 RBI. A party hearty type, Waner was famous for his ability to hit hung over. He gave up the bottle for a year in 1938 at management’s request, and only hit .280, the first time he failed to reach .300+. Needless to say, the tee-totaler experiment ended after that campaign. Another bit of lore was that the Bucs discovered he was nearsighted late in his career and made him wear glasses. He gave those up when he found the large fuzzy object he had been swinging at all those years turned into a small spinning BB that was nearly impossible to hit when he had his peepers on. And finally, Paul and his younger brother Lloyd (Little Poison) hold the career record for hits by brothers with 5,611.
