The Triple-A Norfolk Tides defeated the Toledo Mud Hens, but the Double-A Bowie Baysox lost to the Altoona Curve.
The Single-A Frederick Keys fell to the Wilmington Blue Rocks, while the Single-A Delmarva Shorebirds beat the Hickory Crawdads with a suicide squeeze.
Before today's games, there were several transactions in the Orioles' minor league system.
As I mentioned earlier, Bobby Livingston was promoted to the Tides from Bowie in order to make a start for the injured Chris Tillman. The Baysox later filled Livingston's spot by adding relief pitcher Pat Egan from Delmarva.
The Shorebirds added two players from extended spring training to their roster -- outfielder Brian Conley and pitcher Shane Mathews.
Finally, the Orioles claimed left-hander David Davidson from the Florida Marlins and assigned him to Norfolk. The 25-year-old relief pitcher was designated for assignment by the Marlins on May 22.
This is actually the second time Davidson has been claimed this season. The Pittsburgh Pirates designated him for assignment on April 15, and the Marlins added him to their roster.
Davidson appeared in one game for the Marlins, and he gave up five runs and four hits in one inning against the Tampa Bay Rays on the day he was designated for assignment. He was 0-1 with a 3.00 ERA in 13 games while splitting time between the Indianapolis Indians and New Orleans Zephyrs at the Triple-A level.
Norfolk first baseman Oscar Salazar returned to the lineup after missing three games due to a wrist injury. The 30-year-old utility player was 2-for-5 with a home run and three RBIs.
Tides left fielder Justin Christian was 2-for-5 with a triple and an RBI, while catcher Robby Hammock added two hits.
After being recalled from Bowie, Livingston gave up four runs and 10 hits in six innings. The Tides were leading, 5-4, when the 26-year-old left-hander exited the game, but the bullpen was unable to preserve the advantage.
Norfolk relief pitcher Jim Miller (2-1) suffered a blown save after allowing two runs and four hits in one inning. The 27-year-old right-hander picked up the win, however, when the Tides scored in the 10th. Ross Wolf picked up his first save of the season after tossing a scoreless inning for Norfolk.Bowie Baysox (AA)
Recap: Starting pitcher Jake Arrieta (4-3) allowed two runs and six hits in six innings, and the Baysox suffered a 3-1 loss to Altoona. The 23-year-old right-hander struck out five batters and issued three walks.
Bowie left fielder Jonathan Tucker and second baseman Miguel Abreu were each 2-for-4. Tucker collected a double, while Abreu scored the only run for the Baysox. Center fielder Dave Krynzel also hit a double for Bowie.
Relief pitcher Ryan Ouellette gave up one run and three hits in one inning for the Baysox, and Wilfrido Perez struck out two of the three batters he faced.
Frederick Keys (A)
Score: Wilmington Blue Rocks 4, Frederick Keys 2 (Box score)
Recap:Zach Britton turned in a quality start for the Keys, but they suffered a 4-2 loss to Wilmington. The 21-year-old left-hander gave up two runs (one earned) and four hits in seven innings, but he didn't factor in the decision. He struck out five batters and issued four walks.
Once again, Frederick catcher Caleb Joseph led the team offensively. He was 2-for-4 with an RBI in the loss, and third baseman Tyler Henson added a double and an RBI.
Recap: After scoring two runs in the first inning against Shorebirds starting pitcher Ryan O'Shea, the Crawdads were unable to cross the plate for the rest of the game in Delmarva's 3-2 victory in 10 innings.
O'Shea allowed two runs -- both on solo home runs -- and seven hits in seven innings for Delmarva. The 23-year-old right-hander struck out seven batters and didn't walk anyone.
The Shorebirds scored the game-winning run on a suicide squeeze by catcher Luis Bernardo.
Shorebirds third baseman Tyler Kolodny was 3-for-4 with an RBI and a run scored, and center fielder Xavier Avery added two hits.
Delmarva relief pitcher Brandon Cooney (2-2) earned the win after retiring all three batters he faced in the top of the 10th.
