Sims has been out since late June with an elbow sprain. At the time, it was expected that he would miss about a month, a timeline that proved to be just a tad optimistic. The 27-year-old has been an important member of a Reds bullpen that has been a source of frustration for the club this year. His 5.02 ERA looks high but all the advanced metrics like him better. (3.26 xERA, 3.45 FIP, 3.75 xFIP, 3.19 SIERA) This optimism is borne out by his excellent strikeout rate of 34.9%, although his walk rate is a bit high at 11.9%.
As for Brach, a timeline for his injury is unknown. But a shoulder issue is always worrisome for a pitcher. The 35-year-old has thrown 29 innings for the Reds this year, with a 5.59 ERA, strikeout rate of 24.1% and walk rate of 12.8%.
