"I feel like whenever my stuff is going well, I'll end up letting loose and hitting a guy," said Kaminska, who beaned a pair of batters while taking a no-hitter into the fifth inning Monday. "Not on purpose, it's just one of those days when your arms feels good and everything had good bite to it."
Kaminska kept the Javelinas off balance and turned in his best start of the fall, allowing one hit over five innings in Scottsdale's 7-1 win over Peoria in the Arizona Fall League.
A sinkerballer traded to Pittsburgh from the Marlins in the Gaby Sanchez/Gorkys Hernandez deal this summer, Kaminska struck out five and didn't allow a hit until Tommy Joseph hit a single up the middle with one out in the fifth.
"I felt really good," he said. "I started warming up in the 'pen, and it's just one of those ... outings where everything was on and felt quickened. I was throwing to [Yankees catcher Austin] Romine, I was throwing everything for strikes, where I wanted it, in every count. I had good success doing it."
Kaminska pitched around a hit batsman in the first and struck out the side in the second. By the third, he knew he hadn't allowed a hit.
"I didn't let it bother me," he said. "You're not going deep into these games, so you don't worry about it."
Even with a strict pitch count -- he threw 46 of his 68 pitches for strikes -- the reality of walking away from one of your best starts still isn't easy.
"It's definitely something where you want to hand it over and let [the bullpen] do their job, but everyone has to get innings. This a league where everyone is working on stuff."
Kaminska was acquired by the Pirates on July 31 from the Marlins after going 6-4 with a 5.24 ERA in 33 games between Double-A Jacksonville and Triple-A New Orleans prior to the trade. After joining the Bucs, Kaminska went 3-0 with a 2.25 ERA in five games -- four starts -- between Class A Advanced Bradenton and Double-A Altoona.
Now he's trying to take the next step in his development in Arizona. A reliever with Miami, he's back to starting with Pittsburgh.
In four AFL starts, the Ohio native is 2-1 with a 2.00 ERA. He's allowed just one earned run in his last 14 innings.
"You meet a lot of cool people, good baseball players and you have a great defense behind you," he said. "It's a very cool experience and it's a lot of fun."
David Adams (Yankees) led the offensive charge for the Scorpions, doubling twice and plating three runs. That total accounted the most RBIs thus far for the 25-year-old, who is working on a transition from second to third base during his time in the AFL.
Giants' top prospect Gary Brown went 3-for-4 with a run scored from the top of the Scottsdale lineup.
Jeudy Valdez (Padres) ended the Javelinas' shutout with an RBI double in the top of the eighth off Scorpions reliever Dan Burawa (Yankees).
