Liriano looked great early, retiring the first six batters he faced, but then surrendered four runs on four hits and a hit-by-pitch in the third inning.
He was also hit hard that frame, as Travis Snider hit a two-run double off the right-field wall before Travis d'Arnaud added a two-run double of his own that landed just short of the wall in right.
"I think I was rushing out there like I always do," said Liriano, who has a 4.50 ERA in eight Grapefruit League innings. "I was trying to throw too hard with my fastball and made a couple of mistakes. I was missing my spots."
Liriano was frustrated after his outing, and he talked with bullpen coach Rick Stelmaszek about what he needs to do to improve.
"He told me to calm down and relax and try not to overthrow," Liriano said. "I can't get mad at myself like that. He had to calm me down. I was kind of rushing and trying to do too much. I was mad that I was missing my spots."
