He returned to throwing soon afterward, but later reporting said the blister initially affected his ability to throw two secondary pitches and that blister issues continued during the regular season. CBS Sports, citing Mike Petraglia of CLNSCincy, reported in October that Singer missed no regular-season starts.
What happened in spring training?
On March 18, Singer exited his start against Colorado after throwing 51 pitches, 35 for strikes, over 3 2/3 scoreless innings. MLB.com reported that the blister was on his right index finger. Head trainer Sean McQueeney went to the mound with acting manager Freddie Benavides and acting pitching coach Matt Tracy. Singer described leaving as precautionary.
He said the temperature in Arizona was 100 degrees and that he had never pitched there in such heat. “I just didn’t want it to open up and all that,” he said. Singer also said he had never had a blister happen before and wondered whether the heat or air was a factor. That was his speculation, not a medically confirmed cause. MLB.com’s March 18 report and Singer’s comments in that report describe the exit and his concern.
When did Singer return, and did he miss starts?
MLB.com reported that Singer threw a 78-pitch exhibition outing against Milwaukee on March 23 without an apparent blister problem. On March 24, he was expected to make his scheduled March 29 regular-season start against Boston. That was the outlook reported at the time, not a separate medical clearance. MLB.com’s March 24 update

The October report says Singer missed no regular-season starts. That answers the narrow availability question: the cited reporting does not identify a missed regular-season start because of the blister. It does not mean he had no blister trouble during the season.
What did the blister affect during the season?
In April, Singer told FOX19 that his finger felt fine and the blister was “totally fine.” Manager Terry Francona said Singer’s velocity had been down since the spring blister. FOX19 later reported in June that the spring blister initially affected Singer’s ability to throw two of his secondary pitches. The report does not identify those pitches in the available account.

On October 2, CBS Sports/RotoWire reported that Reds president of baseball operations Nick Krall said Singer was plagued by blister issues during the season, citing Mike Petraglia of CLNSCincy. The syndicated item provides no direct Krall quotation and does not specify when the issues recurred, how often they occurred, what treatment Singer received, or how they affected individual outings.

Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Did the blister cause Singer’s 2026 results?
No cited report establishes that it did. CBS Sports/RotoWire reported Singer’s 2026 regular-season line as a 5.85 ERA, 1.59 WHIP, 126 strikeouts, 62 walks, and 157 innings. Those numbers describe his season, but they do not prove that the blister caused his results. FOX19’s June coverage also discussed other performance context, including a May foot comebacker, velocity, command, and pitch results; those are separate factors, not evidence that the blister explains his statistics.
