The White Sox are selecting the contract of right-hander Jonathan Stiever, per various reporters (including MLB.com’s Scott Merkin). Right-hander Alex McRae was optioned to the club’s alternate training site, while southpaw Carlos Rodón is being transferred to the 45-day injured list to open space on the 40-man roster.
Steiver will make his MLB debut this afternoon, getting the start against the Tigers. Chicago’s 2018 fifth-round pick, he’ll make quite a leap to the highest level after topping out in the High-A Carolina League last season. That’s not been uncommon in this year without minor-league play. The former Indiana University ace has been quite good in the low minors, putting up a 3.59 ERA with 193 strikeouts (10.0 K/9) against just 36 walks (1.9 BB/9) in 173 professional innings.
Along the way, he’s caught the attention of prospect followers. Keith Law of the Athletic placed Stiever fourth among Sox farmhands preseason, lauding his plus control and well-rounded repertoire. MLB Pipeline (6th), Baseball America (8th) and Fangraphs’ Eric Longenhagen (8th) all agree that Stiever is among Chicago’s top ten prospects.
Rodón’s IL transfer likely isn’t as ominous as it may initially sound. He was originally placed on the 10-day injured list back on August 4 with soreness in his throwing shoulder. He’d thus be eligible to return from this latest stint on September 18. Rodón is reportedly gearing up for a mound session tomorrow and hopes to return to the active roster this season.
