"I said the whole goal was to be ready for April 5," he said. "It felt good to get out there, I felt fine. I'm going to continue to get my timing, continue to work to get in shape. I felt good playing five innings."
Jay had prepped for his debut by facing Adam Wainwright and Lance Lynn in simulated games earlier in the week.
"Those are two of the best guys out there, and it felt good to go out against a proven pitcher like Bartolo [Colon] today," he said. "I felt good, but I didn't want to push it too much. I feel like we've got a little time window there. I feel I have enough time to get ready."
Jay has spent a lot of his time coaching the team's young outfielders.
"I told my wife the other day that I felt like I've been a coach for three weeks," he said. "I'm getting there early and getting all my stuff done by 11 o'clock. Then it was almost like I became a coach after that. It's something I enjoy doing. It keeps my mind fresh. All the younger guys want to get better and it's kind of cool. [I'm] just trying to do my part."
