"I felt good, fastball command wasn't great, obviously," Morrow said. "I was falling behind some guys, but I was one pitch away from a scoreless inning in the third, they smacked it into left, and a couple of bad pitches later, they had three runs.
"It wasn't terrible, but the further I get along, those mistakes are going to turn into good pitches. The important thing is that I felt good again."
Unlike previous springs, Morrow is throwing all of his pitches early in camp. He threw a handful of sliders, three changeups and a curveball during Toronto's 6-4 loss, but the focus remains on the location of his fastball.
That will be the main point of emphasis during his next start and is something he'll continue refining before the end of the spring. It isn't ideal yet, but that shouldn't be alarming with more than three weeks remaining until the start of the regular season.
"That's the biggest thing at this stage is fastball command," Morrow said. "Just trying to get that to where I want it before I worry about how the other stuff was. I thought I threw some good sliders, I threw some flat ones, too, that were in the strike zone.
"I only threw one curveball, but it was a swing and miss for strike one. I threw a couple of changeups. They have been really good, so I was trying to keep it in the zone today, and I threw two for taking strikes and one that was hit between first and second."
