Jurrjens designated for assignment

BALTIMORE -- The Orioles designated right-hander Jair Jurrjens for assignment on Friday afternoon, meaning the organization has 10 days to trade him, release him or have him clear waivers.

Signed to a Minor League deal this offseason, Jurrjens -- who competed for a rotation spot this spring -- pitched in two games for Baltimore, allowing four earned runs in 7 1/3 innings. In 16 starts for Triple-A Norfolk, the former All-Star went 6-6 with a 4.18 ERA in 16 starts.

"At his young age, I wouldn't close the door," manager Buck Showalter said of the 27-year-old Jurrjens, whose previous injuries caused a snag regarding a big league contract with Baltimore this winter.

"Jair still has a chance to pitch competitively up here. He has shown periods down there, it's just been inconsistent ... sometimes the physical part of it takes a while to come. Someone may be old and the golden goose when it hits. It's all about timing sometimes."

Jurrjens could still remain in the organization and be outrighted back to Triple-A if he clears waivers.

Asencio makes season debut, Stinson sent down

BALTIMORE -- Seeking right-handed relief help, the Orioles selected the contract of Jairo Asencio from Triple-A Norfolk prior to Friday's game, optioning Josh Stinson to clear a spot on the 25-man roster.

Asencio, 30, is 4-0 with an International League-leading 20 saves (in 25 chances) and a 2.15 ERA in 34 appearances with Norfolk this season. He was named an International League All-Star and has struck out 41, walked seven and recorded 27 scoreless appearances.

He made his Major League season debut in Friday's 8-5 win over the Blue Jays, pitching a scoreless seventh inning with two strikeouts. He allowed a leadoff walk and a one-out single but struck out Jose Bautista and Edwin Encarnacion, both swinging, to end the inning.

"Asencio has been pitching well all year down there, wanted to get a look at him and get a feel for what we have down there before the end of the month," manager Buck Showalter said, referring to the July 31 non-waiver Trade Deadline. "There's something we are going to need there that you can't provide from within."

Showalter also said the club wanted to keep Stinson -- who was recalled prior to Wednesday's game -- on a semi-regular pitching schedule. The right-hander last started for Norfolk on Saturday, and got the ball in Friday night's game. He allowed one run in five innings with five strikeouts to earn the win in the Tides' 4-1 win over Charlotte.

"He's coming off two or three really good starts, and we don't want him waiting for someone to fail before he comes in and pitches," Showalter said. "There was a bullpen game going on [Friday for Norfolk], just thought it'd be good for him."

The Asencio addition gives the Orioles another right-handed power arm, something that has been missing since they traded Pedro Strop. Acquired in a March trade with Milwaukee, Asencio held Triple-A hitters to a .174 average this season, limiting left-handers to a .484 OPS and right-handers to a .569 OPS. His unintentional walk rate of 1.19 per nine innings is also top in the International League. In 39 career Major League appearances with the Braves, Indians and Cubs, Asencio has a 5.23 ERA.

To clear a 40-man roster spot for Asencio, the Orioles designated Jair Jurrjens for assignment.

O's have no last-minute agreements with picks

BALTIMORE -- The Orioles didn't have any last-minute agreements leading up to Friday's 5 p.m. ET deadline to sign players from June's First-Year Player Draft, with Baltimore able to ink 32 of the 41 players they selected.

Baltimore signed every one of its picks from the first 14 rounds, 15 total players, including its top pick, high school right-hander Hunter Harvey. The Orioles, whose final agreement was left-handed high schooler Daniel Ayers (25th round), signed all but two in the first 20 rounds, with high school shortstop Tyler Walsh (15th) and Cal Poly right-handed pitcher Reed Reilly the exceptions.

Overall, the Orioles signed 18 pitchers and 14 position players including three catchers in the first six rounds, in scouting director Gary Rajsich's second year with Baltimore. The Orioles top pick in last year's Draft, right-handed pitcher Kevin Gausman, has already had two separate stints in the big leagues in 2013.

Worth noting

• The Orioles acquired Minor League right-hander Tim Alderson from Pittsburgh in exchange for infielder Russ Canzler, who was designated for assignment on July 6. Alderson is 3-1 with a 2.79 ERA in 22 relief appearances for Triple-A Indianapolis this season with 38 strikeouts and 10 walks, and he will report to Norfolk.

• It appears Chris Dickerson (left shoulder) will be able to avoid the disabled list. Dickerson, a late scratch from Wednesday's lineup, tested his swing on Thursday and reported feeling better, with no plans for an MRI. He was available on Friday, but did not play.

• Nate and Lindsay McLouth will be "going to bat for BARCS" by helping to promote shelter pet adoptions on Monday from 4-6 p.m. ET at the Baltimore Animal Rescue and Care Shelter (BARCS) located at 301 Stockholm St., in Baltimore. Anyone taking a tour of the shelter while Nate and Lindsay are volunteering will receive an autograph from Nate.
