... if you love the double play, Bobby Doerr might be your man. In 1949 he led the league by grounding into 31 of them while helping turn 134. And he did this all in 139 games. The middle of the last century was the high watermark for double plays. There were about 6 1/2 singles a game, as well as 4 walks a game. A lot of guys on first base.
