Quite possibly. I think he'll learn, but he needs to learn fast. The big takeaway is focusing on analytics over the feel of the game. But it's also incomplete analytics. For the first game, there's logic to the idea that the particular matchup was bad and that you don't want a pitcher to face a lineup the third time. But that doesn't take into account that you have a five run lead and that you have to play a 162 game season and can't use your whole bullpen in the first game when you have comfortable lead. You let your pitcher pitch because, even if he gives up a two run homerun, you'll still be better off against the remaining batters and your bullpen might be needed when a pitcher struggles in game three.So ... Gabe Kapler in the running for most incompetent manager in history?
In other news, the Minnesota Twins are a bunch of babies because they're upset someone bunted to break a one-hitter during an infield shift. First, no one cares about a one-hitter, bunt all you want. Second, bunting to beat the shift is a great idea and more teams should do it. It certainly doesn't break some unwritten rule. There's a better argument that the shift breaks some rule.
