The list of pitchers who have dominated the Orioles is long and mostly distinguished.

It includes top-of-the-rotation studs like Jon Lester and CC Sabathia, who give everybody fits, but are a combined 30-2 in 39 career starts against the Orioles, and less heralded pitchers like Matt Garza (9-1) and Dallas Braden (5-1, 1.41 ERA)

Toronto Blue Jays left-hander Ricky Romero's numbers against the Orioles aren't as dominant, but he's quickly working his way on that list. Romero allowed just two Mark Reynolds homers, including one of the longest in Camden Yards history, over eight dominant innings as the Orioles went down 7-2 in front of an announced 13,824 on a steamy afternoon in Baltimore.

"He's had our number, man," said shortstop Robert Andino in one of the day's bigger understatements.

Romero's gem assured the Orioles (44-67) of another series loss. They haven't won a series since taking two of three from the Cincinnati Reds June 24-26. The Orioles have lost all four series against the Blue Jays this season and are 7-23 against them over the past two seasons.

"It's frustrating because it's something that, we'd like to win all three," said Orioles manager Buck Showalter. "Where we are, we need to make up some ground just from a W and L standpoint."
