"It wouldn't be fair to me to talk about what we're going to do right now," Hurdle said. "I will tell you this, we're holding pat."
Hurdle said the hot bats of Garrett Jones and Xavier Paul convinced him a roster move wasn't necessary. Jones hit a three-run home run in Thursday's 5-4 win over the Astros, while Paul went 3-for-3 and finished a triple short of the cycle on Wednesday.
"When we had talked about adding, we had a couple guys that weren't really in good places from the left-handed side of the plate," Hurdle said. "Garrett has picked it up. Paul has picked it up."
Pittsburgh will play three-game Interleague sets at Cleveland, at home vs. Baltimore and Boston, and at Toronto.
