Reds GM Nick Krall said Wednesday that Mahle is not on the trade block, Bobby Nightengale of The Cincinnati Enquirer reports.
The trades of Sonny Gray, Jesse Winker and Eugenio Suarez have led to speculation that other Reds players might get dealt, and Mahle and Luis Castillo both have trade currency and are starting to get more expensive - Castillo more so. However, for now, neither starter will be changing teams.
