White Sox left-hander , whom they selected out of the Red Sox organization in the 2023 Rule 5 Draft, underwent a nerve decompre sion procedure in his left shoulder this morning, manager Pedro Grifol announced ( via Sox Machines James Fegan). The Chicago skipper also revealed that free agent signee is dealing with a calf strain, but the team is hopeful hell still be ready for Opening Day. The current hope is that Drohan will be able to begin a throwing progre sion by the end of camp, though that will obviously depend on how his shoulder responds in the early stages of his recovery. The 25-year-old southpaw posted excellent numbers with the Red Sox in Double-A to begin the 2023 season before struggling to a 6.87 mark in 89 frames upon being bumped up to Triple-A Worcester. That sample of 89 innings was the first point of real struggle for Drohan to this point in his profe sional career. Hed posted a combined 3.57 ERA up to that point, leaning heavily on a plus changeup that makes him particularly effective against right-handers. The Sox havent Gleyber Torres Jersey provided a timeline for Drohans recovery, though hell certainly open the season on the injured list. Hell accrue big league service time and pay during that time. His status as a Rule 5 pick prevents him from being optioned to the minors. Drohan will need to spend the entire season on the White Sox big league roster and/or injured list with 90 days on the active roster in order to shed his Rule 5 status for the 2025 season. If the White Sox want to drop him from the roster at any point, hed need to be placed on waivers and, if he clears, offered back to the Red Sox for a nominal sum of $50K. Brebbia, 33, signed a one-year, $5.5MM deal that contains a mutual option earlier this offseason. Hes expected to be in the late-inning mix in Chicago after the Sox dismantled the bullpen with offseason trades of and (and, prior to the summer deadline, trades of , and ). Over the past two seasons in San Francisco, Brebbia has posted a 3.47 ERA with a 22.5% strikeout rate and 7.1% walk rate. He picked up 24 holds in that time and mightve logged more, had it not been for his frequent usage as an opener on the teams patchwork pitching staff. If Brebbia is forced to the injured list to begin the season, an already unsettled Sox bullpen will be even more wide open. Veteran lefty signed a big league deal this offseason and is a sured one spot. Righties , and are out of minor league options and likely have an inside track on another three. Southpaw is an option, but earlier this month about wanting to honor the southpaws desire to build up as a starter. The Sox have a large stable of experienced veterans on minor league deals this spring, with , , , and among their NRIs in camp. Trade acquisition , waiver claim and draftees and are all on the 40-man roster as well. Jonathan Loaisiga Jersey
