I love this Golden article so much I may post it in a couple of threads. It goes through the mechanics of what they are trying to get the hitters to do. Golden expresses some shock at how much more they are doing than
Dave. here's the 1st 3 paragraphs, focusing on pregame prep:
https://www.thebanner.com/sports/nationals-mlb/washington-nationals-home-opener-team-reuild-ZPYD6GTOOJB4BMLW3CKHDADEJI/On Wednesday afternoon, before the Nationals’ series finale against the Phillies, CJ Abrams and Luis García Jr. sat like two schoolkids in their chairs, using their lockers as makeshift desks. With paper and pen in hand, the duo leaned over and wrote on a sheet, occasionally turning to each other for help.
Before each game, the Nationals’ hitters have homework. They each fill out a sheet of paper titled “Go Zones,” which contains two rows of five miniature strike zones. Each zone has a specific area highlighted in green with the word “GO.” Each hitter checks the areas he’s looking to swing at. There’s space at the bottom of the paper for players to leave notes. Then they talk as a group through their game plan.
“It’s a mental thing,” Abrams said. “It starts in practice. Whenever you’re taking BP, whatever your go zone is, just stay there. And, if it’s thrown somewhere else, take it. … And then in the game you just got to go out there and hit, stay disciplined.”
It's CJ and Luis. These might have been the last 2 guys I would have expected to take to this kind of homework. You can't quibble too much with the results for CJ, and Garcia is hitting pretty well too. Whether it's the prep or the natural skill, you can decide.
Golden talks about how several ideas on incorporating data were around under Davey and Rizzo but just not really incorporated. He notes that the hitting coaches used to have to go up to the suites to talk to the analysts before games and the analysts were rarely allowed to talk directly to the players. That changed under DeBartolo.Golden talks about more changes in pregame prep and player reaction.
The article has a lot and is worth a read.
