The Triple-A Norfolk Tides play on the road against the Gwinnett Braves, and the Double-A Bowie Baysox visit the Harrisburg Senators.
The Single-A Frederick Keys meet the Salem Red Sox, while the Single-A Delmarva Shorebirds take on the Greenville Drive.
The short-season Single-A Aberdeen IronBirds host the Mahoning Valley Scrappers at Ripken Stadium, and the Rookie-level Bluefield Orioles face the Greeneville Astros.
Right-hander Chris Tillman was originally listed as tonight's starting pitcher for the Tides, but left-hander Chris Waters is now scheduled to make the start.
Tillman is now expected to start tomorrow night's game for the Tides. With the Orioles' scheduled off day tomorrow, this puts the 21-year-old starter back on the same rotation as right-hander Jason Berken.
Let the speculation begin on whether Tillman will be starting for the Orioles on Tuesday night against the Kansas City Royals at Camden Yards. He would have four days rest after making tomorrow's start.
Tides outfielder Joey Gathright was placed on the disabled list yesterday, retroactive to July 19, with a hamstring injury. Teammate Justin Christian was also added to the disabled list recently, so it's a good thing the team signed Victor Diaz earlier this week.
