1. Would be interesting to see what a arbitration hearing is like. If I was representing Hiura, I would argue that he's already got 1000 PAs in the major leagues since being drafted in June of '17, and the most homeruns of anyone drafted since.
2. I don't buy that argument all, its nonsense. Mayyyybe in April it had some merit; however, this is a team that is trying to win as many games as possible. They're going to play the collection of players they believe gives them the best chance to win regardless of the weight of the contracts. To wit, they've already eaten a ton of money this year in guaranteed salary to Lorenzo Cain, Dinelson Lamet, Jake McGee, etc. Most importantly, if you take a look at McCutchen's numbers, he got off to a terrible start, but since June 1st he's been terrific with a .280 average, .365 OBP, .478 SLG%. In other words, since June 1st there has been NO reason to play Hiura in front of McCutchen. Also its probably not a coincidence that when McCutchen started to hit in early June also coincided with the time period around which Hiura was again demoted to add a pitcher.
3. I don't know if having "hit all his life" means very much. All major league hitters, raked in high school and/or college and the minor leagues otherwise they wouldn't have made it in the first place. Really, its Hiura's lack of defensive ability and the strikeouts that are holding him back neither of which he's showed any ability to improve upon. To be sure, after nearly 1000 PAs in the major leagues, Hiura has had his "chance" to prove himself. In a way, Keston is fortunate he's with an uber patient organization like the Brewers as I'm sure there are teams who already would have cut bait.
