Wilken-DiTuri-O’Rae can get moved yesterday as far as I’m concerned, but I don’t think they have a ton of trade value.
Quintana I’d hold, especially after the second-half of the season improvement he made on both sides of the ball. Real short stops with his power potential just don’t get traded.
Areinamo should be in demand, like Barrios was this past season. It would hurt to lose him but he could be a nice piece in a package.
Same with Baez, especially after his showing in Arizona.
With a 3-5 year big-league keystone combo of Ortiz-Turang likely not interrupted unless by big-time prospects Pratt-Pena-Made-Quintana, the team, imo, can afford to package 3 of the 4 prospects you listed along with the 2 I listed.
