BALTIMORE -- Just two days ago, Orioles pitcher Jason Berken made his Major League debut and picked up his first career victory along with it.

Now, it'll be another Oriole's turn to step onto the mound and into the spotlight for his first Major League start.

David Hernandez, a 23-year-old right-hander, will make his first start for the Orioles in Thursday's 7:05p.m. ET game against the Detroit Tigers.

Having faced the pressure of a big league debut on Tuesday, Berken has some advice for the fellow rookie.

"The advice I got before was [to] try not to change anything," Berken said. "You just need to do what got you here. The thing I tried to concentrate the most on was throwing strikes and pounding the zone. The last thing you want to do is try and chip corners and nit-pick at stuff, so just go out there and attack the zone and try to throw as many strikes as you can."

In Tuesday's outing, Berken lasted only five innings, but allowed just two runs while earning the victory. In eight games this season for Triple-A Norfolk, Hernandez has compiled a 3-1 record and a 2.91 ERA. He has allowed 33 hits and just 13 walks, while striking out 60. The right-hander was the Orioles' 16th-round selection in the 2005 First-Year Player Draft.

Though Orioles manager Dave Trembley couldn't release the name of Thursday's starter, he did drop a hint as to who would take the mound.

"Yeah, the guy who struck out 14 the other night," Trembley chuckled. "I can't spell it for you, but you know who it is. I mean, gosh darnit, do you want me to put the name into a hat and you can pick it out? He's starting tomorrow."

Along with trying to pick up his first career win, Hernandez will look to help the Orioles extend their season-high three-game win streak. The Orioles completed their first three-game sweep of the season on Wednesday with a thrilling 12-10 extra-inning win over the Toronto Blue Jays.

Pitching matchup
BAL: RHP David Hernandez (MLB debut)
Hernandez will be the second Oriole in less than a week to make his big league debut when he replaces the injured Koji Uehara. Hernandez struck out 14 batters in his last outing at Triple-A Norfolk and has posted a 3-1 record and a 2.91 ERA through eight starts. Hernandez led the Eastern League in strikeouts last year and currently ranks second in the International League in that category.

DET: RHP Armando Galarraga (3-4, 5.74 ERA)
The Tigers and Galarraga continue to work on the issues that turned the team's Pitcher of the Month for April into a struggling pitcher in May. After going 3-0 in the opening month, he's 0-4 with a 9.92 ERA in his past five starts, having allowed 25 runs on 30 hits over 22 2/3 innings. He was somewhat better in his last outing on Saturday, allowing four runs to the Rockies on six hits over 5 1/3 innings, but his crushing blow was a Todd Helton solo homer he allowed immediately after the Tigers had tied the game.
