Starting pitcher Wei-Yin Chen struck out 12 Oakland batters — setting a major league record for the most by a Taiwanese-born pitcher in a game — and the Orioles' bats came alive in a 6-1 win over the A's on Sunday at Camden Yards. Chen's 12 strikeouts were also the most by an Orioles pitcher since Erik Bedard tied a franchise high with 15 on July 7, 2007.
