The White Sox have announced that right-hander Dylan Covey has been placed on the 10-day injured list due to inflammation in his throwing shoulder. Righty Thyago Vieira is coming up from Triple-A Charlotte to fill Covey’s spot on the 25-man roster.
Covey has a 4.58 ERA over 37 1/3 innings this season, starting seven out of his nine appearances for Chicago. The 27-year-old hasn’t missed many bats (5.3 K/9) while also posting a 4.82 BB/9, so between those numbers and a generous .239 BABIP, ERA predictors paint a significantly downcast view of Covey’s performance — 5.66 FIP, 5.84 xFIP, 6.12 SIERA.
Covey moved into the rotation when Carlos Rodon was lost for the season due to Tommy John surgery, and Covey’s absence further thins out Chicago’s pitching mix. Depending on how long Covey is out, the White Sox may be able to get by without a fifth starter altogether, as the club only plays eight times over the next 11 days. Beyond that, Odrisamer Despaigne is the only experienced option available at Triple-A, and he would need to be added to the 40-man roster. Of course, the White Sox also have one of baseball’s top pitching prospects in Dylan Cease, though it remains to seen if the Sox will promote Cease (and burn valuable service time) this season or wait until 2020.
