White Sox Reinstate Aaron Bummer, Outright Tobias Myers

The White Sox announced that reliever Aaron Bummer and third baseman Yoán Moncada have been reinstated from the injured list prior to this afternoon’s game against the Mariners. Outfielders Adam Haseley and Mark Payton were optioned to Triple-A Charlotte to create active roster space. Bummer had been on the 60-day injured list, so the Sox needed to clear a 40-man roster spot for him. That’s been achieved by sending righty Tobias Myers — whom the club hadn’t previously announced was designated for assignment — outright to Charlotte after he went unclaimed on waivers.

Bummer is in position to make his first MLB appearance in three months. The left-hander last pitched on June 7, then landed on the IL with a left lat strain a couple days later. Bummer’s absence led the Chicago front office to target southpaw bullpen help in advance of the trade deadline, and they eventually sent catcher Reese McGuire to Boston for Jake Diekman. Bummer will reassume his role as the primary lefty for acting manager Miguel Cairo, as he’d been off to another strong start. Through 17 2/3 innings, he posted a 3.06 ERA with a solid 26.3% strikeout rate and an elite 58.3% ground-ball percentage.

Moncada missed the minimum amount of time after suffering a left hamstring strain during the final few days of August. It was the third IL stint of the year for the switch-hitting infielder, who also landed on the shelf with an oblique injury and a strain of his other hamstring earlier in the year. Those injures have seemingly prevented Moncada from getting into any sort of groove, as he’s slumped to a career-worst .197/.269/.313 line over 324 plate appearances this season.

The Sox added Myers on deadline day, claiming him off waivers from the Giants. The 24-year-old has started five games with Charlotte since then, allowing a staggering 16 runs (15 earned) with 11 walks and eight strikeouts. It’s the continuation of a nightmarish season for Myers, who has worked exclusively at Triple-A between the Guardians, Giants and White Sox organizations. He owns a 7.35 ERA in 71 frames between the three clubs’ top affiliates.

Those struggles have come largely out of nowhere, as Myers posted a slid 3.90 ERA with a huge 30.5% strikeout rate in 117 2/3 innings between Double-A and Triple-A in 2021. That led Cleveland to acquire him from the Rays last November and immediately add him to the 40-man roster to keep him from being selected in the Rule 5 draft, but things have since unexpectedly gone backwards. Myers, who has yet to make his MLB debut, will now have to try to work his way back onto a 40-man roster. He’ll be eligible for minor league free agency at the end of this year if Chicago doesn’t first reselect him onto the 40-man.
