Dennis Patrick Aloysius Lyons (1866-1929) was a strong hitting third-baseman over a thirteen year career in the major leagues from 1885 with Providence to 1897 with the Pirates. His lifetime batting average was .310. In 1890 he led the American Association in on-base percentage and slugging, and was second to Chicken Wolf in BA. He hit 62 home runs in the Deadball Era and was known as a formidable fielder in the no-glove era. Lyons’ era was also a time of rapid evolution in the game. In 1887, the year Denny “hit” safely in 52 straight, the pitcher’s box had been tightened and the pitcher’s delivery shortened to one step. Walks were also considered hits that year which has caused most modern students of the game to dismiss his “streak,” second only to Joltin’ Joe. But DiMaggio didn’t have to hit a fastball hurled from fifty feet. Only two of the 52 games was affected by walks but they were in the middle of the run. Despite such quibbles, Lyons was clearly a very accomplished player both offensively and afield.
