Totally understand that some guys cannot be helped. But something isn't adding up. How does Reed go from hitting 156 in the majors to immediately 447 at AAA. Bregman who was crushing at 2 levels and starts 1 for 28. Worth who was crushing at AAA bats 179. White who kills it at AAA soon to fall below 200. Tucker who was killing it at AAA holds a 167 avg. Moran managed all of 2 hits in 19 ABs. Kemp did okay but not great. Literally no one who has been called up this year has worked out. Unless you want to call Marisnick a call up, but in his case he didn't hit for anything in AAA so there wasn't any fall off there. Marisnick is probably the best case for someone to hang their hat on I guess.
You have over simplified a very low number of at bats, and grouped to many people into one category.
Reed has struggled to look good at the plate, that is true. Alex Bregman struggled with his batting average early, but he has not been overmatched at the plate, he has been putting good swings on balls. But, part of baseball is that every player goes threw periods where balls that are hit well, turn into outs, and they can't buy a base hit, but also go threw periods where even the balls that are poorly hit, drop in. To judge a guy just by batting average off of 28 AB's, is not realistic. Danny Worth is not really a prospect, he has had 300 career atbats. Most with the Detroit Tigers, and he has not shown yet an ability to hit major league pitching. Tyler White has struggled, no doubt about it, but he was never considered a top Prospect to begin with. And Right now, Preston Tucker looks like the guy he was last year. When he is hot, he is hot, when he is cold, he is ICE COLD. And unfortunately he is COLD more than he is hot. Tony Kemp is now hitting .271, with a .353 OBP. It sure seems to me that Tony Kemp is showing all the signs of "working out" just fine.
