Chatwood's four solid frames represented the longest appearance for the right-hander since he underwent Tommy John surgery in 2014. He allowed three hits and struck out two.
"I felt good," Chatwood said. "The biggest thing was I got better as I went along. The second time through the lineup, I felt sharper, so that's a big thing for me going forward, building the confidence up."
The only runs charged to Chatwood came courtesy of Padres shortstop Jemile Weeks, who continued his torrid spring with a two-run homer in the first. Weeks could very well be playing his way into a utility role on the Padres' roster.
