Today many MLB teams utilize numerous types of defensive alignments depending on the batter in order to gain a defensive advantage.
Which MLB manager was the first to implement an infield shift for his defense in order to gain said advantage?
Wikipedia says that this first happened in the 1920's, but apparently became most famous when employed against Ted Williams by Eddie Dyer.
Minor supplemental info
"The only year that [Cy] Williams didn't bat .300 over that span was 1923, when he batted .293 and blasted 41 round-trippers to take over the NL career home-run record from Roger Connor. National League managers recognized that the best defense was to play him extremely deep and around toward right field"
It seems like "infield shift" would be one of those things logged as an item of interest in a sports article, but I can't find anything definitive.
