Rangers' Dane Acker: Held back in extended ST

Acker (undisclosed) is on the 7-day injured list at High-A Hickory.

According to Jim Callis of MLB.com, Acker is in extended spring training, so he may just be getting held back as he slowly ramps up in an effort to manage his workload. The 24-year-old righty only logged 25.2 innings split between rookie ball and High-A last season as he returned from Tommy John surgery.
