BALTIMORE (Reuters) - Baltimore rookie pitcher Chen Wei-yin outdueled postseason maestro Andy Pettitte to guide the Orioles to a 3-2 victory over the New York Yankees on Monday and tie their American League Division Series at one game each.

Chen, who was born in Taiwan, gave up eight hits over 6 1/3 innings while surrendering two runs, only one of them earned, on a chilly night in front of more than 48,000 raucous fans at a sold-out Camden Yards.

A two-run single by Chris Davis in the third inning and a run-scoring base-hit by Mark Reynolds in the sixth provided the offense for the Orioles.

Pettitte, who holds the Major League Baseball record for postseason wins with 19, gave up seven hits and three runs over seven innings and took the loss.

Robinson Cano had a run-scoring double and Derek Jeter an RBI single for the Yankees, who had nine hits but left 10 men on base.

The best-of-five series now shifts to New York with Game Three set for Wednesday.
