Hendriks (elbow) was placed on the 15-day disabled list Tuesday.
Having last pitched Saturday, the 27-year-old Hendriks will be eligible to return from the disabled list May 23. Despite owning a 19:1 K:BB ratio, he's surrendered a whopping 16 runs (15 earned) in just 16.1 innings over 11 appearances. His elbow may have been contributing to the struggles, but poor BABIP luck was also factor.
