My book "everycubever" comes out in April and features a mini-bio of every Cub who ever played. I spent a good week researching today's birthday boy intrigued by his nickname...
~Johnny Butler 1893–1967 (Cubs 1928)
They called him Trolley Line, and Johnny more than likely acquired his nickname thanks to the town of Butler, Pennsylvania, which featured a well-known Trolley line (the Butler Short Line). Butler didn’t have much power (3 career home runs), and he didn’t hit that well (career .252 hitter), but he was a pretty good glove man in the infield, and he was versatile. Trolley Line Butler played 3B/SS for 1928 Cubs. He stayed in the big leagues for four seasons–two years with Brooklyn before joining the Cubs, and one season with the Cardinals in 1929. By the turn of the decade, the Trolley Line was shut down.
