LOS ANGELES — The Orioles made a flurry of roster moves before their interleague series opener against the Los Angeles Dodgers, including recalling left-handed pitcher Jayson Aquino from Double-A Bowie and outfielder Dariel Alvarez from Triple-A Norfolk.
To make room for the two players, the Orioles optioned left-hander Ariel Miranda to Triple-A and placed designated hitter Pedro Alvarez on the three-day bereavement list.
Aquino, who was acquired in an April 7 trade with the Cardinals for cash, was 4-7 with a 3.25 ERA in 14 appearances (13 starts) with Bowie. He will replace Miranda — who was with the major league club for just one day, allowing three runs on four hits over two relief innings Sunday in Seattle — in the Orioles bullpen.
The Orioles are Aquino's sixth organization —his fifth since the end of 2014 — but he will be making his major league debut if he gets into a game.
"Right now, I'm very happy," Aquino said. "It's unbelievable for me. It's been seven years, changed with six teams. For me it's different. Just working hard every time, every day. Just thank you to Baltimore for [bringing] me to major league baseball."
The 23-year-old Aquino pitched to a 2.25 ERA in five June starts, holding opponents to a .215 batting average.
"Miranda wouldn't be available for three days, wanted to make sure we had a fresh arm down there," Orioles manager Buck Showalter said. "It was Aquino's day to pitch, anyway. I'm pretty proud we came out of four tough days pitching, and we have just about everybody available today."
Dariel Alvarez, a 27-year-old Cuban outfielder who debuted with the Orioles last season, was hitting .271/.309/.363 with 21 doubles, three homers and 33 RBIs in 82 games for Norfolk.
"Dariel's been consistent down there," Showalter said. "He's done pretty well."
Miranda joined the Orioles on Sunday in Seattle when the club optioned right-handed starter Tyler Wilson to Triple-A following his shortest start of the season.
Pedro Alvarez is slated to miss all three games in Los Angeles following a death in his family. He left the team following Sunday's game in Seattle for the Dominican Republic for a funeral. Showalter said he will be back with the team Friday.
The Orioles can add a different player for each day a player is on bereavement leave, so if Aquino pitches extended innings, the team could option him and replace him with another arm in Alvarez's spot.
O'Day could be ready shortly after break
Showalter said the next few days will be pivotal in determining whether right-handed reliever Darren O'Day (right hamstring strain) will be able to return from the disabled list on or around the time the club resumes play after the all-star break on July.
"Darren had another good day today," Showalter said. "The problem is because it's such a post-up leg in his delivery, you've got to make sure it's healed before you start … he's throwing, but he's not driving off his leg like his delivery does. Hopefully, that's moving in a really good direction."
O'Day has progressed slowly since a bullpen session didn't go well in San Diego last week. He threw his first bullpen session between games of a doubleheader in Baltimore on June 25.
"It's possible," Showalter said. "I think the next two or three days, if we like where we're going, he won't have much of an All-Star break."
McFarland out three to four weeks
Orioles left-hander T.J. McFarland, on the disabled list with a left knee sprain, likely won't be available to return until late July, Showalter said.
The team placed McFarland on the DL Thursday in a series of roster moves. He is 2-2 with a 5.63 ERA in 15 appearances this season.
He was roughed up in his last appearance, Tuesday in San Diego, allowing five of the seven batters he faced reach base (three hits, one walk, one hit batter) and yielding three runs over one inning of mop-up duty during an 11-7 Orioles win.
McFarland's injury is a re-aggravation of a knee injury that forced him from a start at Triple-A Norfolk on May. He pitched to a 1.69 ERA at Norfolk following his return.
Around the horn
Former Orioles farmhand Steven Brault, who was traded to the Pirates as part of the Travis Snider deal, will make his major league debut against St. Louis on Tuesday. Brault was 2-3 with a 2.31 ERA in nine starts for the Pirates' Double-A and Triple-A clubs. ... The Orioles made their first trip to Dodger Stadium since 2004 — and their second overall — since sweeping the Dodgers in the 1966 World Series. The Orioles were swept here in three games in 2004 and entered Monday's series opener 3-6 against Los Angeles in regular-season contests. … The special jerseys and caps the Orioles wore for the Fourth of July will be autographed, authenticated and auctioned off on orioles.com/auction. Proceeds will benefit the USO of Metropolitan Washington-Baltimore (USO-Metro). The auction ends Thursday at 10:00 p.m.
