Cole had said some muscles in his back tightened up while he was pitching Friday. Both he and Hurdle downplayed the issue after the Pirates' 8-2 win against Philadelphia, saying Cole's removal was more of a cautious move than anything else.
"It just got a little tight," Cole said Friday night. "Instead of trying to push through it, coming back, it just seemed like the right thing to do, to take a step back for a minute."
Cole cruised through his five innings before exiting, giving up no runs on one hit. He also had five strikeouts in the start, his second since being activated from the disabled list with right shoulder fatigue, which caused him to miss a little more than three weeks in June.
On Saturday afternoon, though, it did not appear the latest bump in the road would force Cole back to the DL. Cole (7-4, 3.78 ERA) was scheduled to start again Wednesday in St. Louis.
