The Chicago White Sox are making a series of roster moves involving relief pitchers ahead of their first series back from the All-Star break.
The White Sox will call up Reynaldo Lopez from Triple-A Charlotte and Aaron Bummer will return from the injured list before the weekend series vs. Houston begins. To make room for those two on the roster, the club will option Jace Fry and Matt Foster.
Getting Bummer back in the mix is a positive development for a White Sox bullpen that endured its share of struggles throughout the first half of the season. The southpaw recorded a 3.26 ERA and 43 strikeouts across 30.1 innings of work between multiple injury list stints before the All-Star break. Bummer is expected to be a lockdown option near the end of games, so a strong start to the second half of the season is crucial for him and the White Sox relief corps as a whole.
As for Reynaldo Lopez, this call-up incites a "last chance to prove it" feeling. His numbers in Charlotte have been downright bad in 2021 -- 1-6, 7.62 ERA, 50 K, 21 BB, 1.879 WHIP, 4.8 BB/9 in 39 innings across ten games. After an uninspiring 2020 season (6.49 ERA), Lopez fell out of favor among White Sox hurlers and began the season with the Triple-A club. As James Fox of Future Sox and James Fegan of The Athletic noted above, Lopez will presumably assume a relief role with the White Sox. 2021 is the last season of White Sox club control over Lopez before he enters arbitration years, so the front office likely wants to get another look at the righty before deciding on future plans.
