So far, the Orioles have reason to be thankful for Pavano's snub.
After throwing 14 2/3 scoreless innings in spring training to earn the final spot in the Orioles' rotation, Chen (1-1) opened the season last week by allowing two earned runs in six innings at Yankee Stadium.
For an encore Friday night, the left-hander struck out three and walked one in his second career complete game in 70 starts. He retired his first seven batters and 11 in a row before Hideki Matsui singled in the seventh.
"I'm very proud. The Yankees are a very tough team," Chen said. "I felt like I was throwing strikes, changing speeds and keeping the ball down. I felt really good."
He outpitched Pavano (0-2), who chose to sign with the Yankees during the offseason after being courted as a free agent by the Orioles. Both of Pavano's losses have come against the Orioles.
The right-hander yielded seven runs, three earned, and seven hits in 5 2/3 innings.
"We didn't give him very much to work with," Yankees manager Joe Torre said. "I can't say he ran out of gas. They just caught up to him."
With the score tied in the sixth, Tejada and Sosa connected to put the Orioles up 3-1. After an error by second baseman Rey Sanchez, Luis Matos and Brian Roberts hit two-out RBI singles and Tejada drew a bases-loaded walk from Felix Rodriguez.
Sosa then drove in two runs with a ground-rule double for an 8-1 lead.
"We had a good pitching duel out there," Chen said. "Then we exploded in the sixth inning and gave me that cushion I needed."
Chen's only other complete game came last Sept. 13, a five-hitter against Toronto.
Sosa's home run was the 576th of his career and second this season, the first at Camden Yards since he joined the Orioles as a free agent in February. He has now homered in 42 ballparks.
"It's not about that. It's about winning games," Sosa said. "No question, what I like about this team is every day we're going to have a new hero. We're comfortable with that."
Tejada and Sosa each had two hits and three RBI, and Roberts went 3-for-5 to lift his batting average to .429.
"That's the best game we've played all year," Tejada said.
The Orioles are 3-1 against New York this season. Last year they started 0-7 against the Yankees and finished 5-14.
Bernie Williams drove in the lone run for the Yankees (4-6), off to their worst start since 1991. With Alex Rodriguez at .205, Jason Giambi at .219 and Tino Martinez hitting .182, New York is batting .254 as a team.
"We have a lot of people here who have been through this before," Williams said. "It's too early to press. It will turn in our favor because we have a lot of talent."
"It's tough after what, game 10, to say, "Oh, my God. What's going on?" the manager said. "Unfortunately, when you're expected to do a better job than we're doing, it becomes more of a surprise."
The Orioles went up 1-0 in the first when Melvin Mora hit a one-out double and scored on a triple by Tejada, his seventh consecutive game with an RBI.
New York tied it in the third. Martinez walked, went to second on an infield hit by Sanchez and scored on a single by Williams. The Yankees came up with just two more hits the rest of the way.
In the Orioles' half, Roberts hit a leadoff triple and Mora was hit by a pitch before Tejada looked at a third strike, Sosa hit a popup and Rafael Palmeiro grounded out.
- Roberts has hit safely in all 10 games this season.
- The Yankees have trailed in nine of 10 games.
- It was the first time in seven games the Orioles failed to get at least 10 hits.
- Rodriguez has one hit in his last 16 at-bats, and Derek Jeter is in a 2-for-18 skid.
