The White Sox announced Friday that they’ve designated right-hander Chris Volstad for assignment. His spot on the 25- and 40-man rosters will go to right-hander Tyler Danish, whose contract has been selected from Triple-A Charlotte. The ChiSox also called up right-handed reliever Thyago Vieira from Charlotte to join the big league bullpen.
Volstad, 31, has soaked up 47 1/3 innings for an ugly Chicago pitching staff so far in 2018, though he’s posted an ungainly 6.27 ERA with 5.5 K/9 against 2.3 BB/9 in that time. Those 47 1/3 frames are the most he’s totaled in a big league season since 2012; in fact, it’s a greater total than the combined number of MLB innings Volstad threw from 2013-17. The Sox have a week to trade him or run him through outright waivers, and it stands to reason that there’s a good chance he’ll clear and have the opportunity to remain in the organization at Triple-A.
Danish, 23, was one of Chicago’s better pitching prospects for a few years but cleared waivers and was removed from the 40-man roster last offseason. He’s had a nice run in Charlotte this season, though, notching a 3.06 ERA with 6.4 K/9, 3.6 BB/9 and a 51.1 percent ground-ball rate in 64 2/3 innings of work. All but two of Danish’s 29 appearances have come in relief, so it seems the organization will see how the former starter fares out of the bullpen moving forward.
As for Vieira, the 25-year-old flamethrower has had his struggles in Charlotte this year — his first in the organization. Chicago picked him up in a trade that sent international bonus considerations to the Mariners this past offseason, and while he’s averaged a heart 11 strikeouts per nine innings pitched in 2018, he’s also averaged 5.3 walks in that same span. Vieira averaged 98.7 mph on his fastball in last year’s brief MLB debut with the Mariners, and he’ll bring the ability to miss plenty of bats to the table on the South Side, even if control could prove to be an ongoing issue.
