"You work hard for it and hope to get to this moment," said Quintana through translator and White Sox manager of cultural development Jackson Miranda. "I just wasn't expecting it the way it happened."
Quintana has made nine starts for the White Sox and given up two runs or fewer in eight of them. He already has surpassed his single-season innings high by four with 106 thrown between Double-A Birmingham and the big leagues.
But the 23-year-old southpaw is trying to enjoy the success and continue it, as opposed to worrying about that workload increasing.
"I'm not worried about it. My arm feels good," Quintana said. "I definitely have reached the limits of what I pitched last year, but since my arm feels good, I feel like I can double whatever I did before. I feel all right.
"It has been an incredible first half. I'm really excited to be contributing to the team, and I'm hoping that this can continue on to the second half of the season. It's about being mentally prepared for every fifth day and continuing with the routine I've been doing and I should be fine."
