Kreidler is easily the best defensive player on the roster. A comment above on how this affects James Outman is interesting. I think the Twins see this as just a 10 day placement with no other moves. Bringing up an outfielder, ostensibly for better offense, would definitely have a ripple effect though. The Twins can't really promote a prospect from AAA and let him sit on the bench. Emmanuel Rodriguez (as an example) would need to play every day or 5 times per week. Right now Austin Martin is showing that he can field, run, and get on base. Martin should be in the lineup at least 5 times per week. What does that then mean for Larnach or Wallner. So I think the Twins just keep Outman.
Does Kreidler play at all except for once a week? He is a far superior shortstop to Brooks Lee and likely creates an out or three per game more than Lee. However, Lee is the shortstop and pretty young, which means it is unlikely he is replaced. Seems like Kreidler will mostly sit or play a little third base despite the obvious benefits of him playing shortstop.
Kreidler has basically been Royce Lewis at AAA. He has drawn walks, strikes out, can run, hits a couple extra base hits but is not a bat to watch. Lewis is a Twins love story whose draft position trumps many realities of his tough career thus far. Kreidler can swing from his heels too.
How the Twins use Kreidler will be interesting to watch.
