FAIRFIELD-SUISUN, CALIFORNIA The case of Willie Mays’ missing HR: Will he get credit for Negro League blast? [San Francisco Chronicle] Dec. 21—The magical number 660 overlaps generations of Giants fans. Everyone knowing at least a little about Giants franchise history knows 660 is Willie Mays’ home run total. What if the number jumped to 661? Negro Leagues statistics from 1920 to 1948 soon will be classified among statistics of major-leaguers, and 1948 was Mays’ rookie season with the Birmingham Black Barons. It had been believed Mays had no home runs that year, at least based on statistical websites. Upon further review, he did hit a homer in 1948, according to newspaper clippings and a record of the Negro American League final stats.
