"Of course, you don't want [anyone] to get hurt, but what can I do?" Nova said. "I've just got to take advantage of the opportunity that God gave me right now. It's not the way that you want to be pitching, but there's nothing I can do."
Nova's last outing came in relief, against the Orioles on June 29, when he pitched 5 2/3 innings of solid two-run, six-hit ball to mop up after a rough outing by David Phelps.
Friday will mark Nova's first start since he went into the rotation for a spot start on June 23, when he held Tampa Bay to three runs and seven hits over 6 2/3 innings in a 3-1 loss.
Nova feels as though he is always auditioning for more work.
"It's not good. I don't feel good the way I am right now," he said. "I don't know when I'm pitching [until] somebody gets hurt. It's not the spot I want to be in, but it's something that I can't control."
Nova was in the rotation in April before being demoted to Triple-A Scranton/Wilkes-Barre. He accepts responsibility for his problems, and he is motivated to work his way back to prominence.
"I can say that I put myself in this position," he said. "I wasn't pitching good enough in the second half last year, and the way I started  wasn't good. I did put myself in this position."
