Mike Moustakas is absolutely lost at the plate, and it looks to me like he isn't going to find his swing again at the Major League level. So why aren't the Royals discussing sending him to Omaha to try and figure things out? We've seen it done, and work, before with some of our previous top prospects. In 2008, Butler wasn't hitting at the beginning of the season. They sent back to Omaha for a month in June, and when he came back, so did his bat. On top of that, Moose looks way worse than Butler did when he was sent down.
Anthony Seratelli, the current Omaha 3rd baseman, is hitting quite well for the second year in a row. He currently has a great looking .305/.408/.479 triple slash in 198 PAs this year, and .299/.374/.492 last year. Seratelli is 30 years old, and I don't expect him to be any sort of long term solution, but he would almost certainly be better than what we are seeing out of Moustakas at this point.
Moose currently is worth -0.9 WAR this year, and if it doesn't turn around soon, by the end of the year we could be looking at a WAR value so negative that it would make Jeff Francouer proud. Continuing to give Moustakas at bats is not only hurting the team, it is probably hurting Moustakas himself. Let's not dig a hole so deep that we can't find our way out. Send Moustakas to Omaha, and let him find the bat that made him a top 10 overall prospect 2 years ago.
