I found this while reading mlb.com tonight.
Starting intrigue: The Orioles have yet another doubleheader coming on Thursday and need an additional starting pitcher for that day. Mazzilli said the club won’t go with the bullpen-by-committee as it did July 7 against Tampa Bay. In that game, John Parrish managed just 2 1/3 innings and the entire bullpen was out of whack.
Two intriguing starting candidates are Bruce Chen and John Maine, both of whom are pitching well for Triple-A Ottawa. Chen, who is with his sixth organization, is 3-1 with a 3.06 ERA in 15 games, and 2-0 with a 2.61 ERA in his past five starts. He has 70 strikeouts and just 19 walks in 61 2/3 innings.
Maine, meanwhile, has responded after a slow start. The team’s 2003 Minor League Pitcher of the Year is 4-5 with a 4.26 ERA with 70 strikeouts in 76 innings. He has a 3.22 ERA in his past eight starts with 51 strikeouts.
Since there are 39 players on the 40-man roster, the Orioles do not have to make a roster deletion to add either pitcher.
Farm report: Maine allowed one earned run in six innings but Ottawa lost, 4-3, to Norfolk on Saturday. Darnell McDonald and Jack Cust homered. Maine lowered his ERA to 4.26.
