Farmer is a prototypical utility infielder. He’s the best fielder at 2B and 3B, and a very good SS, who hits acceptably off the bench. Polanco and Castro dont have the same skills, and were the Twins to trade/DFA Farmer, they’d still need a quality fielding utility infielder. Also, Farmer fetched a 26 year old minor league pitcher with a career 4.33 ERA and had to be added to the 40 to be protected from rule 5. Is the trade return likely to be better than that? Or worse with a Farmer’s higher salary and less control?
We can debate how good of a second baseman Polanco and Julien are, but the two of them are both bat-first 2Bs. Neither have shown capability outside of 2B and DH.
Polanco should command a much better return than Farmer, and combined with a prospect could return MLB starting pitching.
my feeling is that combined with the 40 man requirements and the self imposed budget constraint, Polanco makes the most sense in a trade.
edit to add, I don’t want the team to “shed payroll”, but I do want them to get better without emptying the farm. I think Polanco can be “easily” replaced and provide value in trade.
