Given that the White Sox traded all of their proven relievers in July and didn’t have all the replacements waiting in the wings, bullpen seemed to be the most sensible area for MLB-caliber upgrades this winter.
It’s been one that’s slow to develop. The Sox traded for Thyago Vieira — a neat use of international money they couldn’t spend on its original purpose — but he should be allowed the necessary time in Triple-A to finish his development.
When it comes to relievers more likely to be givens on the 25-man roster, though, the Sox don’t have much to show yet for their winter.
