The Triple-A Norfolk Tides play on the road against the Columbus Clippers, and the Double-A Bowie Baysox face the Trenton Thunder.
The Single-A Frederick Keys host the Lynchburg Hillcats, while the Single-A Delmarva Shorebirds will battle the Kannapolis Intimidators.
A few roster moves were announced within the Orioles' minor league system today. Infielder Rodolfo Cardona was transferred to Bowie from the Keys, and infielder Jedidiah Stephen joined Frederick from the Shorebirds. In order to replace Stephen, Delmarva added infielder Garabez Rosa from extended spring training.
at Columbus Clippers (6:35 p.m.)
Norfolk: Radhames Liz (0-0, 3.86 ERA)
Columbus: Jack Cassel (3-4, 6.39 ERA)
* Liz will slide into Norfolk's rotation -- at least temporarily -- to plug the hole created by three starters being promoted to the Orioles. Brad Bergesen made his debut in April, and Jason Berken and David Hernandez made theirs in May. Liz allowed two unearned runs and six hits in 3 2/3 innings against the Toledo Mud Hens during his first start of the season on May 27.
* After winning their past four games, the Tides continue to lead the International League South Division with a 34-15 record. The Durham Bulls (32-18) are 2 1/2 games behind the Tides. Despite losing three straight games to Norfolk, the Clippers (25-26) maintain a one-game lead over the Indianapolis Indians (23-26) in the West Division.Bowie Baysox (AA)
at Trenton Thunder (7:05 p.m.)
Bowie: John Mariotti (0-2, 4.64 ERA)
Trenton: Josh Schmidt (3-1, 1.84 ERA)
* In his last start, Mariotti allowed three unearned runs and four hits in six innings against the Altoona Curve on May 27. The 24-year-old right-hander walked four batters and collected one strikeout in Bowie's 7-3 victory. Mariotti is still searching for his first win at the Double-A level since he was promoted from the Keys in the beginning of May.
* The Baysox (25-22) remain in fourth place in the Eastern League Southern Division, but they are closing the gap with the first-place Akron Aeros (32-16). Bowie trails the Aeros by 6 1/2 games in the division. Trenton (25-22) is in second place in the Northern Division, two games behind the first-place Connecticut Defenders (28-21).
Lynchburg Hillcats (7 p.m.)
Frederick: Pedro Beato (3-3, 4.13 ERA)
Lynchburg: Paul Mildren (2-4, 4.75 ERA)
* In his past two starts, Beato is 2-0 with a 2.19 ERA in 12 1/3 innings. The 22-year-old right-hander allowed one run and six hits in 6 1/3 innings against the Wilmington Blue Rocks during his last start on May 27. Beato struck out a season-high eight batters in five innings against the Potomac Nationals on April 26, but he hasn't had more than four strikeouts in an outing since that game.
* The Keys remain in last place in the Carolina League Northern Division, and they continue to hover at the .500 mark with a 25-25 record. The first-place Hillcats (32-17) have won seven of their past 10 games. They lead Frederick by 7 1/2 games in the division.
at Kannapolis Intimidators (7:05 p.m.)
Delmarva: Rick Zagone (4-3, 1.92 ERA)
Kannapolis: Dexter Carter (1-2, 3.86 ERA)
* Zagone tossed seven scoreless innings against the Hickory Crawdads in his last start on May 26, but he didn't factor in the decision. The 22-year-old left-hander collected six strikeouts and gave up four hits in the Shorebirds' 2-1 victory. Zagone ranks 10th in the South Atlantic League with 52 strikeouts, and he is third in the league in ERA (1.92).
* The Shorebirds (26-20) have won eight of their past 10 games. With this recent stretch of success, Delmarva is in second place in the South Atlantic League Northern Division. The Lakewood BlueClaws (29-20) are in first place in the division, leading the Shorebirds by 1 1/2 games. Kannapolis (24-26) is in fifth place, trailing Lakewood by 5 1/2 games.
