I did make moves to improve my D in in season 2, but season 3 was kind of static. (My season 1 shortstop made 80 errors, but I had no one ready to replace him). This season I have only 1 quality hold over as a starter and 1 guy who has bounced from ML to AAA and back. He seems to have decent numbers (although only a vR of 55, he's a lefty), but gets crushed at the BL level. I have used him as long relief, and has a LH specialist, but he has the stamina and recovery of a starter. It will be a couple more seasons till the young guys reach BL potential.
