Liriano has been healthy, and that is a big reason for his success this season.
"Everything feels good," Liriano said. "Everything feels great and I feel a hundred percent, and I'm just trying to get ready every start and trying to go deep in every game."
Liriano is sporting a 2.92 ERA, and he has recorded 144 strikeouts in 142 innings.
"I always had my changeup," Liriano explained. "I just had trouble locating my fastball before, and I went home and I just worked on my fastball and worked on my fastball in my bullpens, and I have been getting better every start. That makes all the difference."
"Command of the fastball has improved over the years," Pirates pitching coach Ray Searage noted. "It was a problem earlier. Now with the command of the fastball -- he always had good command with his offspeed pitches, the slider and the changeup -- now he's got three weapons to go to war with.
"Now he can pitch inside, which goes hand in hand with the fastball command. Then you can't sit on one pitch with the guy. You have to catch him when he has a bad day, which -- he's going to have them -- but in the long run, he's done a tremendous job for us and he's really grown into himself."
