The bullpen's workload has been somewhat unbalanced in the early going. Closer Rafael Soriano had pitched six times entering play Saturday, including three straight appearances that left him unavailable on Friday. Tyler Clippard also had six appearances and rested Saturday after a rough 35-pitch outing on Friday.
On the other hand, left-handed long man Zach Duke had appeared only once, on April 5, before working a scoreless seventh Saturday. Johnson does not want to start using Duke, his only southpaw reliever, as a situational lefty.
"I haven't got a good system going," Johnson said. "It's a work in progress."
Meanwhile, fireballing right-hander Henry Rodriguez pitched Saturday for the first time in almost a week, walking two and striking out one in a scoreless eighth.
Johnson said prior to Saturday's outing that Rodriguez is "a little behind" some of the other relievers, coming off surgery to clean up a bone spur from his elbow, as well as forearm tightness that limited him early this spring.
What did the manager think of Saturday's outing?
"It's going to kind of be a work in progress," Johnson said. "From no winter ball to that surgery, but he threw the ball good [Saturday]."
