Frelick is out of the lineup for Thursday's game against the Giants.
As Adam McCalvy of MLB.com notes, Frelick fouled a ball off himself during Wednesday's 5-3 win and was removed from the contest in the top of the eighth inning, but his early exit seems to have been mostly precautionary. McCalvy characterized Frelick's absence from the lineup Thursday as more of an off day rather than the result of legitimate concern about his health, so the expectation is that the 24-year-old will be back in the lineup for Friday's series opener in Cincinnati. Garrett Mitchell will spell Frelick in right field Thursday.
