Right-hander Jake Arrieta came into spring camp as one of a host of candidates for an open spot in the Orioles’ starting rotation.

There was no question is his mind, though, on who would win the competition: Him.

“No, absolutely not. Whether that's cockiness or overconfidence, whatever you want to call it. that's just the way that I personally had to approach the situation, with that mindset," he said. "Knowing that I had to go out and actually show it and not just know it in my mind. I think the combination of having that mindset and knowing I had to kind of prove myself helped me get to the point where I am now.”

Arrieta had the best camp of an Orioles pitcher, allowing just three earned runs in 17 1/3 innings (1.56 ERA), striking out 16 and walking eight batters. He’s had success in spurts before, but the 27-year-old said he is better equipped to maintain consistency this year.

“I’m much more focused and much better prepared this time around, Not that I wasn’t prepared or [didn’t have] focus going into this last season,” said Arrieta, who was 3-9 with a 6.20 ERA in 24 games (18 starts) for the Orioles in 2012. “But I think my preparation and focus is a little bit more fine-tuned. And now I am in this position and am ready to take the bull by the horns, so to speak, and keep my job all year. I think that’s what everybody wants and what everybody expects from me. That’s what I plan to do.”
