"Just getting a feel for those. Pitching to both sides of the plate and getting a little bit of competition in and getting the juices flowing a little bit," said Sale of his start. "It felt good. I felt like I wasn't quite as jittery as normal.
"I just tried to stay as calm as I could and not overthrow. Not try to make anything too nasty and that kind of stuff. Just the normal going out there. Just locating and getting a feel for my changeup and compete a little bit."
Sale plans to build up the slider during his upcoming bullpen session and throw more in his next start Wednesday against the Padres.
