Arrieta making noise from Triple-A

Arrieta making noise from Triple-A

NEW YORK -- Touted Orioles prospect Jake Arrieta tossed eight innings of one-run ball at Triple-A on Monday night, continuing to make a case that he's Major League-ready.

"It's not my call," Orioles manager Dave Trembley said when asked if Arrieta's performance in the Minors is becoming too good to ignore.

"We've gotten good reports on him. I'm sure [president of baseball operations Andy MacPhail] and everyone else is aware of what he's doing and what the proper timeframe is."

The 24-year-old Arrieta is 6-2 with a 1.91 ERA in 11 starts and is holding International League opponents to a .183 batting average. The right-hander has allowed two earned runs or fewer in five of his past six starts and has kept his walks -- an organizational concern -- in check, having issued just two free passes in each of his past three outings.

"I honestly think that [the Orioles] know that I'm ready to pitch in the big leagues," Arrieta said in a phone interview with "For me, it's just a matter of having a spot open or whatever it might be.

"I think that they've noticed something with me down here, so we'll see what happens."

One of Arrieta's rotationmates at Norfolk, Chris Tillman, was recalled and made his season debut in Toronto on Saturday, assuming the roster spot vacated when the O's moved David Hernandez to the bullpen. But the 22-year-old Tillman is on Baltimore's 40-man roster while Arrieta is not, meaning a promotion for Arrieta -- even to join the team's beleaguered bullpen -- would involved some roster shuffling.

"We'll have to see where that takes us," Trembley said. "I know [Arrieta has] done a nice job. I guess he says he's ready. That's nice to hear. You need confidence to compete up here. I don't think he's lacking in that area, which is good for a young guy."
