Peralta isn't too worried about his spring statistics.
"Yeah, it's kind of normal for me," Peralta said. "I always have a rough Spring Training. I only care about the health of my arm, my body. I cannot tell you a Spring Training where I had really good numbers."
Actually, Peralta, 28, has had one good Spring Training -- in 2017 with the Brewers, he posted a 0.71 ERA in 12 2/3 innings. But his overall ERA in Spring Training is 5.49.
"When the lights turn on, it's a different story," Peralta said. "I only have to think about getting people out. Here, you're working on certain things. But I feel really good."
And Peralta said the conversion to the bullpen is going well.
"It's a little bit different," he said. "But I feel like I'm used to it right now.
"The only thing I really care about down here is if my arm is feeling good and my velo is good. The pitches here don't move as much as they will in Kansas City or somewhere else in the league with normal air. Here, with the dry air, the ball doesn't move as much."
Peralta's velocity here has been in the 95-97 mph range.
"When it gets warmer and the air is normal," he said, "I'll be up there to 97-98-99. You'll see."
