Christina De Nicola of MLB.com reports that the 24-year-old Cuban hurler is trying to overcome fatigue in his left arm, an unwelcome symptom he started feeling two outings ago.
The southpaw says he has experienced fatigue two or three times before, most recently in 2011. He has worked in 17⅔ innings over his career high. He stated the obvious in the MLB.com article, nothing this is not the best time to experience arm fatigue.
"I wish this would've happened earlier in the season, because this is the time of the season when we're on the final [stretch] of the season and I would like to be better," Chapman said.
