BALTIMORE, Sept. 27 (UPI) -- Bernie Williams registered his 100th RBI with a single in the sixth inning and Andy Pettitte tossed five scoreless innings Friday night as the New York Yankees handed the Baltimore Orioles their 10th straight loss, 6-2.
New York improved baseball's best record to 101-58 and has a magic number of two for gaining home-field advantage against Oakland in a potential American League Championship Series. The Yankees are trying to avoid a makeup game with Tampa Bay on Monday that would be played if New York is a half game behind Oakland after Sunday's contests.
This game was scoreless until the sixth inning. Jason Giambi stroked an opposite-field single with two outs and moved up on a wild pitch by Baltimore starter Sidney Ponson (7-9). Williams followed with a single.
Williams notched his fifth career 100-RBI season and became the third Yankee to score and drive in 100 runs this season, joining Giambi and Alfonso Soriano. The last time New York had three players with 100 runs and 100 RBI was 1932, when Babe Ruth, Lou Gehrig and Ben Chapman accomplished the feat.
Pettitte (13-5) improved to 9-2 lifetime at Camden Yards as he tuned up for the postseason by yielding just three hits. He escaped a major jam in the fifth inning when Baltimore had runners at second and third with none out. Pettitte got Geronimo Gil and Mike Bordick on groundouts and Luis Lopez on a sharp lineout.
Jorge Posada notched his 99th RBI with a run-scoring single in the ninth that made it 6-0.
