The Baltimore Sun reports that Matt Riley has likely won the No. 5 slot in the rotation.

Riley has allowed just one earned run in his past 12 innings, lowering his ERA to 2.81. He is expected to be given the nod as the fifth starter over fellow rookie Erik Bedard, who is scheduled to pitch tonight. Manager Lee Mazzilli said he's made his decision but wants to tell the players first.

Mazzilli also announced that Melvin Mora will be the No. 2 hitter in the O's lineup.

"He puts the ball in play," Mazzilli said. "He's a gap-to-gap type of hitter. Plus he can hit the ball out of the ballpark. His on-base percentage is good, and that's what I like. I need guys on base for our big guys."

Again, it is great to see Mazzilli stress on-base percentage.
