Brian Matusz felt like he needed one more rehab start before rejoining the Orioles. Now, it's up to the Orioles to decide whether he was right.

Matusz allowed one run on four hits and a walk while striking out seven in five-plus innings for Triple-A Norfolk on Friday night against Columbus. He threw 83 pitches, 53 for strikes.

Matusz started the sixth inning and allowed the first two hitters to reach on singles. He was then removed from the game in favor of Pat Egan, who allowed one of the inherited runners to score.

In three rehab starts -- one at Single-A Frederick, one at Double-A Bowie and Friday's start for Norfolk -- Matusz compiled a 1.80 ERA. He allowed two earned runs on nine hits and four walks while striking out 10 over 15 innings.

"We'll see what the reports are that we get back," said Orioles manager Buck Showalter. "We'll listen to Brian, but we'll also listen to the people that are there. We'll make a decision, I think, by [today]. I know that Brian has tentative travel plans both ways."

Matusz will join the club in Oakland today and throw his bullpen session Sunday in front of pitching coach Mark Connor. If the Orioles deem him ready, Matusz will make his 2011 big league debut Wednesday in the series and road-trip finale against the Seattle Mariners.
