Ross Detwiler, making a rehab start tonight for Triple-A Syracuse against Rochester, allowed three runs, but only one earned, in five innings. The left-hander is returning from a strained right hip flexor and will likely join the Nationals as a September call-up in the next week, if not sooner.
Once he does return to the majors, though, the Nationals’ rotation will get even more crowded. I’d envision the Nationals doing some of the “piggybacking” that general manager Mike Rizzo referred to last month with Detwiler.
They talked about using two starters in several games, since some of their pitchers coming off the disabled list are going to be on tighter innings restrictions. Throwing, say, Yunesky Maya from the right for five innings and Detwiler from the left for four innings could be a way of doing that.
If the Nationals decided to remove Scott Olsen from their rotation, Detwiler could make Olsen’s scheduled start next Tuesday on regular rest.
Maya would be another option, having pitched last night. But we won’t know for sure how the Nationals’ rotation shakes out until they call up a few of these pitchers.
