Berti is starting at first base and batting ninth Monday in Game 2 of the ALDS against the Royals.
The 34-year-old Berti has never played first base before in the majors or minors, but he's been working out at the position in recent days and the Yankees feel comfortable enough with how he's looked there to throw him into the fire. Oswaldo Cabrera -- who started at first base in Game 1 and went 1-for-4 with a double and three strikeouts -- will begin the contest on the bench.
