Hangover from the teens, where it wasn't a matter of if you were going to bunt, steal, or hit-and-run, but when.
The 1915 Baltimore Terrapins had 36 homers, slugged .325 as a team, and had 178 sac hits. They were shut out 16 times and had another 28 games where they scored a single run, and were 0-44 in those games. One-run strategies? Hell yes!
