I couldn't find an ideal place to post this thought. Given the prospects the Twins have who are near ready, and their skills, it may be an ideal time to trade Luis Arraez. There are still three years of service time remaining, he's coming off a batting champion and Silver Slugger season and he's young (25 all of next season). I don't think his value will get much higher.
Two prospects (Martin and Julien) are close to being ready. Both supply speed and Julien has power potential. Both guys look like OBP will be part of their game and will need a place to play. In addition to Martin and Julien, the top two position player prospects (Lewis and Lee) are also infielders.
Luis Arraez is elite at what he does. He takes great at-bats, seldom strikes out and will probably be a .300 hitter for the rest of the decade. He also showed he is reliable in the field. His defensive numbers at both second and first were good last year. I believe if he played regularly at third, he'd be fine there. There are things Arraez is not--he's not going to hit for much power and he will never be speedy. In addition, he's dealt with a lot of leg injuries for a 24-year old. Finally, his second half last year was pedestrian. His walk rate was only about half of the rate in the first half. He also had an OPS of only .685 versus left handed pitching.
An Arraez trade would have to net the Twins quite a bit--proven MLB talent or elite prospects. It also would be a hard sell to the fan base, so I don't know if it will happen, but if I'm the Twins' brass I'd certainly consider it.
